Windows Vista, the update to the operating system due this year, will add a feature called Sidebar. Sidebar is a small panel at the side of the monitor that can be used to view photo slide shows, RSS feeds and other small programs, dubbed gadgets.
While DVD movies have popularised widescreen displays, Windows chief Jim Allchin said there are lots of uses for the extra pixels.
"That's why Sidebar is something important," Allchin, co-president of Microsoft's platform, products and services division, said in an interview last week. "You will be able to put it to the side and just watch it on the periphery, and the widescreen allows this."
Sidebar is one of a number of features that Microsoft has talked about as part of Vista, but has yet to include in external test versions. The next Community Technology Preview release, which is planned for February, is slated to include all of Vista's features, including Sidebar.
"This CTP that we are doing in this quarter will have all the features that we had planned to put in the product," Allchin said. Other features expected to debut in the February test version include a new migration tool aimed to make it easier for people moving their systems to Vista from Windows XP.
Microsoft is targeting the February test release at enterprises, aiming to get early-adopter companies to try out the software on a few hundred PCs each. A consumer-oriented test release, planned for the second quarter of this year, will be made available to "hundreds of thousands, maybe millions" of customers, Allchin said. The final version of Vista is slated to arrive in time to be on PCs sold in the 2006 holiday season.
The Sidebar was part of the original Longhorn vision as first outlined by Microsoft at a developer conference in October 2003. However, the feature was absent from many test builds, leading to speculation that it had been scrapped. Recently though, it has been featured prominently in discussions of Vista features, including Bill Gates' keynote at last month's Consumer Electronics Show in Las Vegas.
Although Sidebar is mainly seen as a consumer feature, Microsoft has talked up the tool as a way for workers to have fingertip access to key information, such as graphical representations of real-time business data.
In addition, Allchin said it offers a nice way to provide alerts to people. These can be sent, for example, via RSS or gadgets, which are mini-applications that reside on the Sidebar.
"You can have nice -- some people might say interruptions, or things that are bothering you," Allchin said. "On the other hand, it's a way to keep noticing what's happening in your business."
The notion of gadgets is similar in concept to the widget idea that Apple Computer uses in the Dashboard feature of Mac OS X and in the Yahoo Widget Engine, which is based on the Konfabulator program Yahoo acquired in July.
Microsoft hopes to spur use of gadgets well beyond the sidebar. In Vista, the same small applications can be used on the desktop display itself and also on the secondary display on the lid of some notebooks -- a feature Microsoft has dubbed SideShow. Microsoft also wants people to run gadgets on their Windows Live pages.
Like Yahoo and Apple, Microsoft has been courting developers, posting information on a special Web site.
