Thinkpads fascinate me, so I spent way too much time researching.

I don't have an X1, but I wonder what is missing, being that thin.
CD/DVD drive and VGA connector, obviously, though these can be
brought along (and lost) as dongles when needed.   How long does
the charge last if doing CPU intensive stuff, like compilation?
Sometimes low power means that some behaviors, like playing videos
and listening to music, are power frugal, but CPU intensive stuff
like computation and encryption drain the battery fast.

The specs are here:

Integrated Intel video.  Probably good, with usable open source
drivers, but you need more information on external monitor and
projector resolution support.  Intel sometimes fails at this.

The hardware maintenance manual is here:

It looks like the battery is accessable by removing the keyboard,
so that can be replaced, yay!  Ditto for the SSD, though it looks
quite nonstandard.   However, the screws are nylon coated and
"use once and replace", so you will need to purchase replacement
screws before you open it up.  As a committed warranty voider,
that would be troublesome for me - I always look inside.

Lenovo still provides the HMM, so that is a big plus.  Many of
the connectors are on accessable "mini-sub-cards", so if one
breaks or wears out, you don't need to replace the whole main
board.  However, the RAM is soldered in.  Great for reliability,
lousy for upgradability.

There is no mention of the X1 Carbon on http://www.thinkwiki.org/
That is the go-to community for all things Thinkpad and Linux. 
No mention on http://www.linux-on-laptops.com/lenovo.html
That is less well maintained.

A review claiming Ubuntu 12.04 compatability, low brightness, and
3.5 hour battery life: http://www.amazon.com/review/R242N9HGY01ZIC

Here's dmesg output: https://gist.github.com/3934585

The actual laptop is small, but the bundle of things you need to
bring along for charging, DVDs, presentations, etc. is big.  My
ancient T60 is a heavy monster, but everything I need (except the
AC adapter) is built in, and I get 6 hour battery life if I carry
two spares.  That gets me across the country.

So ... this looks like the usual perils of early adoption. 
I would wait for other folks to evaluate it and find the bugs
and endure the recalls before I took the risk.
