Windows was fun, well... not really, for a while, but it soon became time to upgrade to something more UNIX-y. I decided to start out with something small, like DSL Linux. I had a problem though, my x120e didn't include an optical drive so I would need some way of booting the system into a live Linux distro. I found the answer is a USB stick with bootable software loaded onto it.
Since I wanted to use Linux as a full time operating system but still keep Windows around in case of an emergency, I decided to swap hard drives using a 60GB drive that I had pulled out of a MacBook a few years ago. DSL wouldn't install, neither would Feather Linux or Knoppix. I thought it might be an issue with the UEFI boot firmware but changing it to the legacy mode didn't seem to help. I eventually decided to go with the most popular distribution I could think of, Ubuntu.
Ununtu installed without a hitch, the wifi worked without any configuring and even the trackpoint on the Thinkpad was recognized. I quickly discovered that Unity was very usable as a day to day window manager and was able to use the entire system as my primary computer for about 2 weeks.
Ubuntu's software center was excellent, I installed DropBox and was able to sync my documents between my Thinkpad and MacBook without any issues. I didn't try out any of the games from the sofware center, but I did experiment with a few themes and window managers.
The overall experience with Linux was excellent, and my computer would still be running it if it wasn't for the strange issue with my wireless conncetion dropping and not picking up again until I restarted the computer. As of right now, I'm back on Windows 7 until I read that they fixed their wireless issues.
