My 2011 X220 refuses to die. It's been tossed in bags, scuffed, cracked, and burned with a candle. The keyboard is perfect. Touchpad is fine. Wifi is excellent. Upgradeability unmatched. I'm running Linux with a tiling window manager, and performance is fine for pretty much everything I want to do, including compilation. It runs super hot (80C+ sometimes), but is always way quieter than my XPS15 from work. Only complaint is the low resolution of the screen (1366x768). 1080p would be perfect for the 12.5in screen.
My sister put a candle on the table and the rising heat was barely under the lip of my open laptop lid. It melted a bit of the plastic, but the damage was only cosmetic. Sorry; pretty anticlimactic I know haha.
