If only they would make a laptop with an AMD processor, no discrete graphics + someone makes a decent keyboard with a trackpoint for it, I'd immediately buy 2, I don't care about the price. It's also likely that I'd be able to convince my employer to switch from thinkpads to this. Btw, it's ironic that the much cheaper T series Thinkpads work much better with Linux and are much more reliable than the X1 series.
Intel processors of this generation are just not energy effiecient and run too hot.
