Gadgets have always taken center stage at the Consumer Electronics Show, but this year more than ever, even the coolest devices seem to be mere means to an end -- access to content and services whenever and wherever you want them.

For years the underlying trend at CES, held in Las Vegas from Monday through Thursday, has been convergence, the increasing connection among communications, consumer electronics and computer industries. This year the stakes have been raised, with new mobile services, devices that connect to wireless broadband networks, and deals between content and entertainment companies and computer vendors.

With the addition of Web 2.0 services and content into the traditional convergence mix, expect the term Convergence 2.0, which pops up occasionally, to be used more frequently in the future.

The diverse array of gadgets and standards at the show can be a barrier to convergence, however. Industry executives acknowledge that despite -- or because of -- the various connectivity technologies on the market, making products work together is still a complicated and daunting task for consumers.

As usual, Bill Gates set the tone with the initial CES keynote Sunday, although this year was the Microsoft co-founder's final appearance at the show. Gates and Microsoft Entertainment and Devices Division President Robbie Bach unveiled new partnerships for Microsoft's MSN, Xbox Live and Mediaroom IPTV services.

They also announced that NBC will use Silverlight technology for video playback and on-demand access to events. In addition, Microsoft is working with TNT, Showtime and CNN to provide IPTV-based services, and announced deals with MGM and ABC to bring content to Xbox Live.

"XBox Live is attracting virtually all the content people because of the volume we've got there and they see this group of very engaged users spending a lot of hours and finding new media in that environment," said Gates, in an exclusive interview with the IDG News Service. "Our announcement with NBC on the Olympics is about our innovations in this Silverlight, where you can view interactive content, multiple video streams."

Yahoo CEO Jerry Yang underscored the importance of mobile services in his Monday keynote, introducing a new look for the company's Go mobile Web interface, and new technology to let third-party developers build mobile widgets for the mobile platform.
