If you want to know if your home printer, wireless mouse, or other computer gadget will work with Windows RT, Microsoft's new tablet-oriented operating system, there's now an easy way to find out.
More than 3,000 items that have been tested for the various versions of Windows, including mice, keyboards, game controllers, MP3 players, storage devices, graphics cards, cameras, and monitors ... you get the idea.
A surprising number of devices work with Microsoft's new operating system but a good number of them are labeled as "limited functionality." Even one of Microsoft's own keyboards, for example, isn't fully supported. But if you get a Surface tablet, you'd probably want one of the special tablet cover/keyboard combos Microsoft sells anyway.
One ironic example: Microsoft used to make an HD-DVD player for its Xbox video-game console. (HD-DVD was an old high-definition disc format abandoned in favor of Blu-ray.) It doesn't work with RT—but it does work with Windows 8.
