Add to that a 250GB SSD and drop the ram to 8GB (for fair comparison) and the price is $1,430. Similar MacBook Air is $1,550. So, for extra $120 you get better screen, much nicer touchpad, light up keyboard, an OPTION to run OSX, and way nicer design.

The X1 Carbon is kind of nice. But same thing applies. Low res screen is a letdown, and by the time you load it up to be comparable to say, rMBP, it's about the same price.

Well, I have observed that boosting your RAM to 16G gives you much better performance because you almost never swap to disk. To get 16GB on a MacBook, you are looking north of $2000.
