it is a good concept but so was the vista aero. in reality it turned out to be a nightmare. I am not happy that with every upcoming version they put more and more restrictions on the os and make things harder to get to. yes i REALLY want to turn off notifications about not having auto updates on and i really want to get to the windows folder and i most certainly would like to be able to find the control panel.
You know what i mean.. Hence why im still running a stripped version of xp almost across the board. So far the only reason i even have 7 is because it plays nice with SSD. But i can put up with it on one system...
We run motion tablets at work and i love the digitizer and loathe the touchscreen. I find it awesome to be able to grab it by the screen so to speak and not press things (then there is the gorilla glass etc etc). Even with palm rejection, it is not accurate in "rejecting" presses and makes handwriting a chore.
For a conventional monitor, i can't imagine having to hold my hand out every few seconds. Might be great way to build muscle (or achieve joint pain) but ill take the proven approach of resting my hand on the mouse.
Multi touch is the devil and it is counter intuitive. Once you use something for a while and novelty wears off, you realize how much it sucks when you just want to get work done!
