Just to add another data point, Arch Linux on X220:
1. 4-6 hrs with 6 cell battery.
2. Yes, Intel everything (HD4000, wireless, etc).
3. Yes, 1 resume crash total this year.
4. Yes, attached to external monitor via DisplayPort -> DVI right now.
5. Never tested.
6. Small, crappy. I'm one of those guys who disables the touch pad in favor of TrackPoint though.
7. Much better IMO, not a fan of chiclet style and Apple's "mushy" keyboards.
