Like the vast majority of home users, I use my PC primarily for Internet/email, games and word processing and, in addition to the user interface, users are interested in stability and speed. Touch screen and metro may work great on a cell phone or laptop but are less than worthless to me or most desktop PC users, especially gamers. First, I don't want greasy fingerprints all over my screen or my hands in the way of seeing the game or content. Also, while Mahjongg or Bejeweled could be played using touch screen, most the games I like simply will not work without a keyboard/mouse or game controller. Second, the search capabilities of Windows is more than adequate already. However, the Task Manager and File Extensions features do look like great improvements. Third, one double click on my desktop icon and I'm where I want to go while Metro users will still be scrolling through search.
The first thing virtually all businesses and most home users will do is get rid of that totally ugly, worthless metro interface and go back to the extremely user friendly, fast and attractive desktop. So Metro should be an option only for those who want it. Try having employees be productive using touch screen and businesses will quickly return to keyboard and mouse. With a keyboard and mouse my hands and arms are out of the way and in the most comfortable position possible. Not so with a touch screen. Ok, so this is pre-beta, but now is the time to speak up and say NO I don't want, need or like what I'm seeing so far and do not want the things I DO want, need and like made incompatible!
