I haven't upgraded my X220 yet since I noticed problems when upgrading
my X200.

I haven't noticed any UI lag (I'm on Xubuntu though, not Unity).

My mai issue is with wifi, it's drops out a _lot_ with Trusty, possibly
this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1316248
but I haven't had a chance to play around with older kernels to test
