The only PCs I see coming with touch screens for Win8 are desktops that incorporate the motherboard and "guts" of the computer into the display (essentially a large standing laptop) or laptops. None of the stand alone monitors being sold are touch screen. For a so called advance in OS, none of the monitor companies seem to be "jumping on the band wagon" or do they know that this is not long to last? And is this why MS gave in and included mouse control at the last minute?
All in one desktops were tried in the past and were not good - no way to upgrade, no room to internally expand, etc. Few kept making them and went back to console designs with separate monitors. So now MS comes along and wants to start this all over again - and there are few desktops to find with touch screens. Of course, MS wants to see an end to the desktop and laptop and get everyone on board with an MS made Win tablet which in business is never going to happen just as big business is sticking with Win 7.
And the funny thing is that MS developed what could be the best screen control system for their Xbox - the no touch, move your hand in the air controller. This actually has great potential and could be added on to a desktop if so designed - but no, MS went to touch screen so that your kids can smear jelly and peanut butter all over your monitor when they use your PC.
