Certainly better than W8 from what little I've seen. Whereas of the previous versions Vista was little more than XP that looked like W7, W7 was basically Vista done right and W8 was still essentially W7 hidden behind an enormous heap of junk that looked just weird, this one seems to be best described as W7 that looks like W8 without all the oddities so... but I still hope they'll do something to the UI, the flat colours are a bit boring.
One thing is certain though, if the rumours are true and W10 is delivered via Windows Update to all W7 and W8 owners, I'll be turning the automatic updates off. Not that I don't want it eventually but I want to be exactly in control of the time when it happens.
