On a Core2Quad Q6600 with 8GB RAM - 80GB SSD, 3TB on USB 3 external drives.
It's awful. It's actually slower on my PC than Windows 7. The new start screen even with dual monitors, one being touch is irritating. Having your old jump list icons on your desktop feels like going back to Windows 2000 again.
Gave it a day, now downloading Win 7 from VLSC again.
Tried it on a tablet and SMART Board and it's fine. For a desktop/laptop power user - nope.
