I've been using Win8 since the CP and now the RP on my work and secondary home machines. I actually find Win7, although great, starting to lack in other areas and there's a couple things I don't get;
1. Why do people have such a hard time with the Start Screen, get over it, it's actually not that bad! Yes, I work in enterprise and have dual screen monitors and are a power user. I'm also good at building bridges and getting over things.
2. Why does everyone think Win8 is just Win7 with no Start Menu. Seriously, if that's the only thing in it for you then you are not a power user or anyone that has a need to take advantage of all the other impressive technologies in Windows 8. I can't be arsed typing up a list for you - http://www.lmgtfy.com/?q=windows+8+features
3. Touch, or more correctly "guesture" has-a/is-the future. I watched my 5yo try to change the TV channels on the screen in the back of the airplane seat by swiping left and right - it didn't work of course but she expected it to. With Win8 there are numerous times I go to reach out to my non-touch screen wishing it was touch-enabled!
What MS is doing with Win8 and WinPhone8 is pretty amazing really - all the integration but still embracing choice for what you lay down on top of the foundation. Much greater enterprise support than Apple or Android combined! Don't get me wrong, I like those devices too but this a middle ground that will take advantage of a HUGE install base and will deliver a framework for large application and entertainment development for years to come. Still plenty of work to do but the potential is huge.
I'll be keeping an eye on the Surface Pro myself - that's more a 'no compromise' experience IMHO. Hopefully other OEMs will lift their manufacturing game and perhaps trump what Microsoft has done with their hardware - here's hoping!
Competition is good, humiliating the competition is better!
