Just thought I’d drop a line out there. I’ve been playing around with a Developer’s Preview (pre-beta) of Windows 8. It looks very interesting. The underlying mechanics appear to be very similar, with some notable exceptions, Windows Defender and Secured booting for one, but the UI received a huge facelift. The design approach appears to be with touchscreens and mobility in mind. The Start menu has been shifted to the entire desktop with a tiled approach better fitting a touch screen.
There has been talk that the OS will be able to be installed on a portable drive and run completely from that drive, meaning professionals could take their OS with them, and plug it into a machine with the hardware capable of running it. The Task Manager also received an overhaul.
