Well, the first few times I tried your link it just took me to the Acer home page, so I quit looking. But anyways......
Being "dependent" on Windows 7 is probably bogus. More likely a sales pitch because Windows 7 has some design features to work with a touchscreen monitor. (big deal, just about any OS can be)
One thing I noticed mentioned on Acers site - "*Touch-screen capability requires appropriate software installed on the PC connected to the display. This software does not come with the display." Most likely meaning you needs the "touchscreen drivers". Touchscreens don't care what system they are on as long as you have drivers that work with that particular OS. I'd bet money the "touch" part is made by someone like 3M or ELO, other than that it's just a plain ol' monitor like any other.
So if you are willing to pay $330 or so on it just to "try it", then go for it.
