1. Multi Touch :

It seems that Windows 7, not OS X, will become the first consumer OS to bring multi-touch capability to the masses after all. We were afraid Microsoft will try to sell Windows 7 on the multitouch pitch alone but are, in fact, pleasantly surprised with the implementation. There is an on-screen virtual keyboard and gestures for common mouse actions, like dragging and right-clicking, that work throughout Windows 7 and applications like paint and Microsoft Earth. Click on a taskbar icon to reveal the jump List or draw a”b” in Internet Explorer 8 to go backwards. Gestures are tied into mouse navigation calls, so any Windows application will be able to support multi-touch right way. Windows 7 is multi-touch on desktops done right and Microsoft should be credited for that.
