Since I now have a Windows 8 Phone (Samsung ATIV S 16GB), which I have been really impressed with, both the phone and the OS, I thought I would give Windows 8 another go on my laptop and now I have installed it on my main pc too. So my 3 main devices are Windows 8!
I am starting to really like it, my hand was forced as I want to start building some Windows 8 Phone apps, and you need Windows 8 and Hyper-V for that.
The people and calendar apps are good, syncing round all my devices, and Hyper-V is just great! Especially if you want to try a different OS like Ubuntu etc.
I still miss my Start Menu, but for me atm the pros are outweighing the cons.
