"Noticeable improvements over Windows 8. Great move...."5.0 starson by migggf
Pros: The ability to leave the desktop wallpaper as the "metro" background creates a smooth transition;
The "Windows button" shows that MSFT is listening to customers. I loved the fact that apps are roaming. Integrated SKYDRIVE is BIG.
Cons: Search is a bit more complex;
The concept of libraries seems to be losing space; I love libraries/search context;
Summary: fast and fluid :). Windows 8 looks more like 2 distinct/different environments. 8.1 reduces such impact. a lot of work ahead, though!
