Where iOS falls surprisingly short is in its lack of support for creation of groups. It supports email groups created on your computer or available on your server, but you can't create them on an iOS device. Also, you can't pick a group in iOS's Mail address fields. Instead, you select a group, then open it up to select just one member, repeating this step to add more names -- a really dumb approach. What you can do in iOS is link contact cards to create virtual groups; for example, if you have separate entries for a couple, you can link their cards so that each person's contact information appears in both of their cards.

Android "Honeycomb" both supports groups and lets you create them, though the process is unintuitive: When you add or edit a contact, there's a field in which you can select or create a group. You can't start by creating a group, then adding contacts to it; instead you have to go to each contact in turn. Also, the groups capability is not available for Exchange-based contacts. And you can't send email to groups, so this feature has little value. "Gingerbread" doesn't support groups at all.

Corporate email, contacts, and calendar support. Android "Gingerbread" is significantly inferior to iOS 5 when it comes to corporate email capabilities. That's mostly because "Gingerbread" supports a very limited set of Exchange ActiveSync (EAS) policies, so most corporate Exchange environments are unlikely to permit access. The biggest omission is support for on-device encryption, which is a basic EAS requirement. You can tell Exchange to ignore such policy misses, but that lets any noncompliant device onto the Exchange server -- not a viable option for most businesses.

If you want to use an Android smartphone on a secured Exchange server, you'll need to use a client app such as NitroDesk TouchDown that provides a secured EAS-compatible Outlook-style functions or a mobile device management (MDM) server/client combo. The beta Divide app from Enterproid looks very promising for such management: It creates a separate "partition" on Android with its own EAS-managed email, contacts, calendar, tasks, and messaging apps, so corporate and user environments are kept separate. Plus IT can wipe and set EAS policies on the Divide environment, in the same way TouchDown allows within its app despite the lack of native Android support for those policies. Divide is expected to ship in 2012. Also in 2012, Google subsidiary 3LM will offer on-device encryption and richer EAS policy support to device makers as essentially an add-on layer to the Android OS, so special client software won't be needed for devices using it. Already, Motorola Mobility offers smartphones with such added security.

iOS, by contrast, has all of this baked in, so there is no special software needed nor any waiting required; it's securable now.

Unlike Android "Gingerbread," Android "Honeycomb" does support on-device encryption (though setup is a pain, as I describe later); it easily connected to InfoWorld's corporate server and passed our Exchange ActiveSync policies. I particularly like how "Honeycomb" let me know specifically what permissions I was granting IT over the device -- details not provided by iOS 5. Overall, iOS 5 has a slight edge in Exchange policy support over Android "Honeycomb," but both should work natively in moderately secured Exchange environments.

Also, Android doesn't let you automatically sync Exchange folders; you have to go to each folder and manually update them. By contrast, iOS lets you designate which folders are automatically synced as part of the mail settings.

Both iOS 5 and Android integrate Exchange contacts into their mail apps, so they look at your Exchange contacts database as well as your local database when you enter a person's name in a To or Cc field. (Of course, for Android smartphones, this assumes your Exchange server welcomes noncompliant devices.) Neither iOS nor Android automatically puts Exchange contacts into their Contacts app; you have to add them manually from within an email. This is not a bad thing; it means that departing employees don't have your entire company contacts database on their mobile device, and it keeps the Contacts app from being filled with contacts a user probably doesn't need.

Both iOS and Android support multiple Exchange accounts.

If you use Lotus Notes, you can work with IBM's Lotus Notes Traveler app on iOS or Android if you're also running the Notes 8.5.1 server with the Traveler extensions. Novell likewise offers EAS support for its GroupWise email client via the Data Synchronization Mobility Pack server add-on, allowing access to iOS and Android devices. Again, Android "Gingerbread" access is limited by its small set of supported EAS policies.

The winner: iOS 5, though Android "Honeycomb" comes fairly close overall. But Android smartphone users are very much out of the corporate loop due to the poor native EAS support and lack of on-device encryption in "Gingerbread."

Deathmatch: Applications

It's now part of the popular culture: "There's an app for that." There are hundreds of thousands of apps for iOS, from games to scientific visualization tools. Sure, there's a lot of junk, but you'll find many useful apps as well. Android doesn't have nearly the same library of apps as iOS, but its smartphone app portfolio is now in the tens of thousands, with many useful titles -- and more coming as the OS gains popularity. There are fewer tablet-specific Android apps in the Android Market, though their numbers continue to increase as well.

The native apps included with iOS and Android are comparable, providing email, contacts, calendar, maps and navigation, browsers, a music player, a YouTube player, and SMS messaging (on smartphones only). iOS 5 supplements its iPhone-only SMS messaging app with a proprietary messaging service, called iMessage, for all iOS devices. Thus, the Messages app for the iPhone is now on all iOS 5 devices, providing iMessaging and SMS on iPhones and just iMessaging on other devices. I believe such platform-specific messaging limits iMessage's utility needlessly. It's like being able to call only people whose phone service is on the same carrier as yours. (FaceTime, Apple's videoconferencing app, has the same self-imposed limitation.) I know that iMessage is a clone of Research in Motion's BlackBerry Messenger service that works only among BlackBerrys, but given RIM's precipitous market decline, it's not exactly a model to copy. (And remember, BBM came in a bygone era when BlackBerrys ruled unrivaled.)

Android has no native notepad app, a very odd omission for a mobile device. iOS's Notes app even integrates with IMAP and Exchange servers, so your notes can be automatically synced to and made available from your email. This is an amazingly useful feature, as your notes are always available. Apple's iCloud extends this utility for locally stored notes. iOS 5 also adds a basic task manager, Reminders, that integrates with Exchange's to-do capabilities and syncs via iCloud to iCal on the Mac and Outlook in Windows 7.

The document-syncing protocol introduced in iOS 5, Mac OS X Lion, and iCloud is a game-changer for many business apps. The fact that a Keynote presentation syncs across all my devices, reflecting the current version no matter where I edit it, is a huge productivity boon. As app developers beyond Apple adopt this protocol, it will become increasingly easy to work in a mobile context without all the sync and file-management hassles of today. Google has nothing similar.

Another big deal in iOS 5 unmatched by Android is its enhanced AirPlay support. You can now send your screen image and audio to an HDMI-connectable presentation device attached to a $99 Apple TV, as long as the iOS device and the Apple TV are in the same wireless network. With an iPad 2, you can mirror the entire screen; on other iOS devices, you can use AirPlay only with apps that work with the protocol, such as Keynote for slideshows and Web Presenter for Web demos. This will make it very easy to give presentations from an iPhone or iPad -- and I can see many conference facilities adding an Apple TV to their standard presentation equipment, given its low cost. Android has no such native capability. Some hacks are available, but I can't see those getting widespread use. Some Android devices come with apps that support the DLNA (Digital Living Network Alliance) protocol found in a smattering of TVs for wireless video, but it's a hardware feature added by the phone makers and not consistently available either on Android devices nor on presentation equipment.

Unlike Apple's App Store, the Android Market is not curated, which makes it easier for developers to get their apps listed but has also let cyber thieves create phishing apps that masquerade as banking or other programs to steal user information. Apple's App Store seems to be less at risk to such Trojans. The Android Market is also slower to load than the App Store and not as easy to navigate within the app details.

You're much more likely to find an app you want in the Apple App Store than in the Android Market. But of course, you don't have to use the Android Market to get Android apps. If you want to get down and dirty, you can configure Android's application settings to install apps from other sources.

Multitasking. iOS is often criticized for not providing "real" multitasking. Instead, it enables some services to run in the background, then limits developers to those services, in an attempt to prevent resource conflicts, as well as to maintain battery life and performance. Other app attributes are stored when the user exits and resumed when the user returns. By contrast, Android boasts PC-like full multitasking, whereby default apps continue to run in the background when you take care of other duties.

In practice, I don't see a difference: Both iOS and Android look and work like "real" multitasking in everyday use. However, iOS makes it easiest to switch between apps.

I have noticed that iOS 5 seems more responsive than iOS 4 as you switch apps -- which is easier to do with the new four-finger swipe gestures. In iOS 4, switching apps required pressing Home to go to the home screen or double-pressing Home to open the multitasking dock, then opening the desired app.

The ease of app switching in iOS 5 is really noticeable when compared to Android "Gingerbread," where you have to drill down several levels in Settings to see which apps are active; that list is littered with various Google services that are also running. This Running Services view really isn't meant for daily usage. You can long-tap the Home button to see a list of recent apps, any of which you can then tap to open. That is more like iOS 5's multitasking dock and a better option than the settings drill-down.

Android "Honeycomb" provides an onscreen button to open a dock of running apps -- also similar to iOS's multitasking dock, though with the nice addition of preview screens showing each app's current status. But neither Android version lets you just move among running apps through gestures as iOS 5 can (as does the WebOS-based Hewlett-Packard TouchPad tablet).

App management. Managing apps is also a little easier in iOS than in Android. Android reserves the home screen for a few preinstalled apps, then lets you add other apps to it by tapping-and-holding and then dragging app icons to the desired location, one at a time. Getting to those apps is where there's extra work: In "Gingerbread," you press a grid icon at the bottom of the screen to get the full set of installed apps; in "Honeycomb," you tap the Apps button at the upper right of a home screen. Fortunately, copying apps to the home screen is easy, but the modal switch is still annoying. By contrast, iOS simply adds more home screens as you pick up apps and easily lets you arrange them by dragging them. (You can't rearrange apps in Android's app screen, just on its home screen.)

iOS also lets you add Web pages to the home screens as if they were apps -- great for the many mobile Web pages that are essentially Web apps, such as, the beta version of InfoWorld's mobile site that lets you take quizzes and play our slideshows. Android can add bookmarks only to its browser's bookmarks list.

iOS lets you create app folders, which can be useful to reduce scrolling among home pages. Unfortunately, the folder icons are still too small to make out, so knowing what's in a folder is not always easy. Android also has a folder capability: tap and hold the Home screen to get a contextual menu and tap the New Folder option. To name the folder something other than New Folder, tap the folder to open it, then tap and hold its menu bar to open the keyboard so that you can enter a new name. Yes, the procedure is that awkward.

Both operating systems alert you to app updates and let you download them wirelessly; iOS also lets you manage apps (including their home screen arrangement) and update them via iTunes, so they are backed up to your computer.

One of the app advantages in Samsung's version of Android "Honeycomb" is its widgets feature. Widgets are mini apps that you can place on the home screen, and they can be very helpful, showing the latest email message or Facebook update or the current time in a large clock. Thus, you can see at a glance the current status of whatever you want to easily track. Neither Android "Gingerbread" nor iOS has this ability -- and "Honeycomb"-based tablets from other manufacturers don't have it either, so I can't credit it to Android.

Both versions of Android have long offered a notifications capability. Pop-up notifications make it easy to see if you have new email or other alerts, whatever you happen to be doing. On tablets, alerts appear in the lower right of your screen, not at the top as in Android smartphones. In both cases, you can pull up a notification pane to see recent alerts.
