Good to see the start menu back, but I've been using Win 8.1 before, and it isn't as bad as people say. Quite the contrary, it's better than 7 regarding performance and memory usage. Win 7, being a patched Vista, meaning it's still a memory hog. Quite a few things have been fixed, and it does run much smoother than 7. I've been using it on my laptop, and the only reason I didn't put it on my main computer is that it's impossible to upgrade without a full OS reinstall, which I'm not willing to do yet. Yes, the interface is crap, but it's worth coping with if you need the performance.
