I love x220, but they are far from perfect. Some serious glitches:

- Small & noisy fan - Awful trackpad (but awesome trackpoint) - Low resolution wide screen

I cannot understand why Lenovo is destroying the x2 series. Now they:

- Replaced the standard processor with a ULV one - Removed trackpoint buttons - Introduced island-style keys - Removed ThinkLight

They should have simply improved a bit the glitches i mentioned.
