The new Lenovo X220 has:
- That red eraser-like pointing stick thingy
- Better keyboard noise reduction during Skype calls
- Can't beat the keyboard for typing feel
- It's black
- More battery life
- Bigger hard drive
- No slip exterior (someone I know stuck fuzzy fabric to his Air so he wouldn't drop it)
- More usb ports
- No dongle to external video
- No dongle to Ethernet
Yes, I definitely want to upgrade to the X220 from my rare X201s (which was an upgrade from an X61s, an X60s, and an X40)
