I recently modded the Acer Aspire One with an eGalax touchscreen. initially, windows 7 recognized it, but for the life of me, i could not get it to properly calibrate without installing some beta win7 drivers provided on the manufacturer's site. now it works perfectly, but windows 7 doesn't recognize it as a touch screen anymore? meaning, i don't get any of the win7 features like gestures and the like. just standard touchscreen support. hopefully, this will be improved by the time win7 is officially released, but it until that time comes, eGalax touchscreen users seem to be screwed. keep in mind, i'm not looking for multi-touch support, i wasn't expecting it on what is a relatively cheap mod. but not recognized at all as anything more than a generic input device?
as i said, the eGalax touchscreen as a touchscreen works flawlessly in win7, but not much more.
