I'm using an X220 with 8G RAM + Core i7. I did not buy the SSD-enabled version from Lenovo, but replaced the factory's SATA disk with a 128G SSD I previously had on an X200... Had to hack the disk a little to fit on the X220 though. It's the fastest laptop I've had, screen is super bright, and with the large battery, I get 6-8h hours depending on the use.

I'm pretty much sold on Lenovo/Linux laptops when it comes to development, although I'm pretty sure that the even-lighter Macbook Air would cover 90% of my current needs (after a huge RAM boost ¬¬). Were I more on the run, I'd probably go for the mac. Right now, I need the raw power of the X220. :)

Oh and BTW if Apple started selling ARM based laptops, I'd get one for sure.
