I am now living, 100% of the time, on my Android devices (specifically with my primary work machine now being a Nexus 7). And, despite my love for Linux desktop distributions, I have no plans on going back to using a traditional desktop or laptop anytime soon. The ability for me to be completely mobile far outweighs any inconvenience of going without a traditional desktop.
What I would like to do is walk through exactly how I am accomplishing this for the various tasks I was previously using a desktop for.
Let's start with the obvious: Using an Android tablet for your day-to-day work can be a real pain if you don't have a physical keyboard. Using a touchscreen keyboard is great to get short tasks done on the go, but if you want to get more hardcore work done (be it writing, programming, etc.), you'll want an actual keyboard. I opted to use the Bluetooth Logitech Tablet Keyboard. It's full-sized, portable, has a great feel and comes with a nice stand to put your tablet on, effectively turning your tablet into an uber-portable, modular laptop.
Then there are the apps. Finding equivalent Android apps to do what you do on a standard desktop can be a challenge (other than for things like email, web browsing and instant messaging...those ones are easy as pie). Luckily, there's a lot to choose from. Here are my current apps for every aspect of my life.
Writing: Office Suite Pro. This is the best general-purpose word processor I've found. Quickoffice is also a good choice, but lacks many of the features that I need for my day-to-day work. In fact, this article was written in Office Suite Pro.
Usenet: NZB Leech +. This is a great Usenet binary client that supports all the standard stuff (SSL, queue's, auto un-archiving, etc.). It runs great in the background, too.
Working With Files: Astro File Manager, AndFTP. Astro is an awesome file management tool that takes a little while to get used to (things like swiping the screen from the left to open up different locations took me a while to figure out). The only weakness I found was that its support for FTP servers was...slow. Just very pokey. So "andFTP" comes to the rescue! It's light, fast and works like a charm for up/downloading files with my servers.
Reading: Aldiko, Comic Rack. Aldiko is a great, customizable ebook reader with a few different, nice-looking views and auto-bookmarking across multiple books. That handily takes care of my ebook reading needs. And Comic Rack steps in to take care of my comic book reading needs. Comic Rack is hands-down the most excellent comic book reading experience I've had on any digital device. It has made reading comics on my 7-inch tablet my preferred way to go.
Programming: AIDE, DroidEdit. AIDE is fantastic for doing either Android native development or "HTML5" work. For a pure text editor, though, I prefer DroidEdit. It’s themeable, fast, and it can support multiple open tabs at once. You really can't go wrong.
Which brings us to multimedia production, design and illustration work. For me this means editing audio and video podcasts and designing comics. Let's leave that for a different article, as that topic can get big.
