Never been a fan of the constant mimicking of real life products in Apple's operating systems. Made no sense. It was silly then and as I get older, it is still silly now. iOS needs to grow up and represent the 6 year old that it will be in 2013.
I have been playing around with Windows 8 Pro and once you get used to the different Start interface from any previous Windows release, it is not too bad. It has been very stable thus far. More so than Windows 7 was, which is what I upgraded from.
