Windows Touch in Windows 7 has won Popular Science’s “Best Of What’s New for 2009” Award this year in the computing category. Speaking of Windows Touch – USA Today’s Ed Baig takes a closer look at Windows Touch in Windows 7 and multitouch on PCs in general. He suggests Windows 7 could spur multitouch adoption in PCs. With technology fused into Windows 7, PC companies and software developers can apply their own touches on top of the operating system. On HP's TouchSmart 600t all-in-one PC, for example, you can tap tiles to launch Twitter and recipe applications. In a Rhapsody music application, you can search for an artist or song by "writing" the name directly on the screen with your fingers.
