I know Server 2008 R2 very well but since Server 2012 has the same Metro crap, I'm a hands down hater. Francis in the video says clearly that the desk top is an App and there is no start menu in Windows 8....SPOT ON!!!
I couldn't bear to watch the whole video. I'm happy with my Windows 8 experience. I've upgraded to 8.1 and going ok... getting used to the Metro apps experience. However... since I do a lot of 'real' work on my computer and therefore need easy access to the desktop programs I installed StartisBack. Inexpensive and works a treat. My desktop and Start menu looks just like Windows 7 but I can flip to the Metro Start Screen if I want to.
It's not enough of an improvement to upgrade if you have 7, but as an OS it works just fine, and is definitely worth it if you are buying it brand new. Unless there is some feature they took out between 7 and 8 that I never used anyway but other people appreciated, the big changes weren't that hard to get used to. Lack of a start menu might be a little jarring at first but it isnt so hard to use, and in some instances I even prefer the way it's set up depending on what I'm looking for. Anything that I really need quickly was always on the desktop/taskbar anyway, so the start menu was always more of a fancy search button to me for my less used programs.
But 9.5 times out of 10 (because I love making up fun statistics), windows 8 was barely even a change over 7 in terms of usage and experience. If I didn't know better, I might think both my computers were using 7 by just glancing at it. The biggest changes I ultimately noticed in terms of every day usage were a) the start menu ; b) the task manager ; and c) The renamed file folders
And a lot of that was superficial stuff, a little odd looking but not really much to complain about (I actually liked this task manager better than the one in 7)
