Win 7 or 8

Since Win 8 is not quite ready for prime time (I read maybe October for release) unless you want to play around I would keep the 7. My rule of thumb is wait for at least SP1 before I think about an OS change and only then if the new OS has been tested to yield significant benefits to me.
 
It's to early to tell but I ran 8 in VM and it was pretty awful on a regular PC. It runs pretty much like a tablet would with everything running on launch, nothing closes, just gets cycled out like a phone OS, judging by the task manager. I just hope the ridiculous UI isn't forced on users and it can be easily disabled. I would buy 8 if it has better files system, is more responsive and I can keep the old UI. Otherwise, I'll pass and I imagine lots of people feel the same.
 
You will not ever get a clear answer I have read articles of people loving it and calling everyone haters and articles saying it sucks ala Windows ME or Vista. I have it running in a VM and will say it runs very well but I am really going to miss the start button and Metro is more of an annoyance to me I just want a desktop. It is all peoples opinions at this point. FYI all people playing with Windows 8 God mode still works yay... LOL
