Meh
It looks like they've sorted out some of the issues of Windows 8 but frankly it's going to take more than the implementation of obvious features that should have been in the predecessor (at least) to bring me back to Windows.
I already switched to Mint on my low powered laptop (though the poor thing needs putting out to pasture tbh) and my Desktop install is starting to get a bit more unstable so it's gonna get the Linux treatment too when I can be bothered.
I'm just sick of the MS bullshit. It's going to take something special to bring me back, especially when the alternative doesn't cost anything.
