Is it stable now?
Did they fix and release some service packs?
Did they make some improvements where they finally realized that some nerds want to keep aesthetically pleasing touchscreen interfaces separate from desktop rigs?
Seriously if they want my money, it's completely up to them.
Well, as a nerd you should know that Win8 is a better OS than Win7 from every technical aspect. It's faster, uses less resources, has better memory management and multithreading, shorter boot times, less intrusive updates etc.
Regarding the replaced start menu, you can easily avoid it if you don't like it.
