Controversial
I'm going to be controversial here in that I've actually used Windows 8 in the Release and Consumer preview versions and thanks to Action Pack I have the final release version too. Admittedly having worked in various IT roles for the last 20 years I'm not necessarily your average desktop user but after half an hour of my first experience with Windows 8 I was completely happy with it and the lack of the Start button. I can see why people would want to keep that comfort there but I would say that if you can work without the Start button (remember that the O/S is just the platform for your apps, services and games) then I'd encourage you to do so. I've found Win + R, Win + F, Win + X and Win + D give me everything I need to get right into the guts of the O/S and use it get my daily grind done. To that end I've replaced Win7 entirely on my laptop and desktop machines and by Christ does Win8 run fast! Just saying :)
