I'm on the 3443CTO revision of the X1 Carbon. The "carbon" part of it is starting to fall apart, the palmrest creaks and I really should have bought it a week later when the i7 with 8GB of RAM was available - 4GB and an i5 feels restrictive (what a sad statement on current software optimisation) Oh, and you can only get ~6 hours of battery out of it with very particular settings and a specific power management driver in Windows 8. Otherwise it's 3-4 hours at best.
