I recently purchased a Lenovo X1 Carbon to run Fedora Linux (F17). I made the jump to an Ultrabook in March 2012, but the ASUS I got had some drawbacks: a lousy keyboard, only 4GB of RAM, and a solid-state disk that periodically thrashed.
Pros:
- Good laptop: great and big screen, great weight, still reasonable 256GB disk.
- Back to 8GiB of memory.
- SSD seems to not thrash.
- Good Linux support (as of October 2012).
- Personally, I like the Thinkpad Touchpoint (the eraserhead-like mouse equivlanet) much better than the ASUS’s touchpad. I found I bumped the touchpad all the time, required “disable mouse on type” mode, which really slows down computer interaction.
Cons:
- Bluetooth seems to have shorter range than my ASUS.
- USB ethernet not supported in current Linux (3.5.4 in F17). (But a patch exists.)
FreeBSD
I don’t know about the status of FreeBSD on this hardware as of Oct. 2012.
