How many people on TMO have run Windows 7 on a decent-spec machine in 2009 (>1GHz, 1GB RAM, =>60GB HDD, DX9 capable)?
It's actually pretty good, and rarely if ever crashes.
Explorer in Windows 7 was actually a huge leap forward even if nothing changed much except for the taskbar.
When I tried Metro on Windows 8, it was just terrible. Oh I hope that **** isn't turned on by default, and it checks whether a touch display is attached before turning Immersive Shell on.
Sharp window corners are nice though.
