Correct me if I'm wrong, but doesn't Windows 7 support touch screens?
I don't have such a screen, and I remember 2.5 years ago when I
bought my computer being annoyed because I read that Win 7 supported
them. But maybe I'm remembering wrong.
The laptop I use for work has a touch screen and Win7 so, yes Win7 does
support touch screens. Win8 however seems to have been designed with
considerably more "touch screen" features.
