From what I understand, WinX is mostly about apps (gimmicks), touch screen capabilities, porting Xbox games, interconnecting devices (dumb down the PC) and a blurb on the latest DirectX which no-one has software to exploit.
Sry MS, I like to keep my PC lean to run only the software I want to run. I don't even like rubbing my fingers all over my phone, and would prefer to keep my files, info and actions private. Do I really need a weather.com app if I have internet? Seriously, X is for lazzorz who don't believe in spoons and want to pretend to be Tony Stark.
