My Windows 8 Preview Experience
Drivers: It is windows 7 friendly, so no issue with drivers. Nearly, all windows 7 drivers may easily install on it.
Compatibility: Not very good with old OS, win7 softwares works but some are not working, even i used compatibility option. Popular Internet security is not compatible like Kaspersky internet security, that i trust alot. However, They will work after final release.
Performance: Very Very Good, Using less ram, gaming, HD video playback awsome. Also window intalls in around 10 minutes.
Looks and Features: The main addition is Metro (A tiled icons start which is replacement of start menu), Task Manager, New Copy and paste window and u may pause and resume your opertaion as well as u can examine the graph of writing speed of drive during opertaion.
Conclusion: I get the impression that the Windows 8 operating system is a native tablet OS and its being "ported" to desktops. What a completely retarded idea this is. The reason I love PCs is because of their complexity. I do not want my desktop dumbed down to the level of a damn smartphone. Windows 8 will be largely irrelevant to the users of traditional PC.
