Just wanted to share it with you...
I bought a copy of Win8 three days ago not knowing what to expect. It turned out that it's not really as bad as it would seem. The system is faster then the original Win7 and the workspace (the desktop mode) doesn't differ much from the previous version. Till now it's stable.
The only basic issue I've encoutered was the system upgrade from Win7 - many bugs appeard afterwards so I'd recommend installing Win8 from the scratch. Also it's better not to install free antivirus apps (avast for example) as the system crashes everytime it enters the Web.
if you're using Win8 any tips would be welcome.
