I was thinking about buying a Raspberry Pi, and running Ubuntu on it. I have looked around the web, and a lot of stuff says that it's difficult for it to work on ARM processors. Has anyone figured out how to get a Raspberry pi to run Ubuntu?
From the Official FAQ Page at Raspberry Pi:
What Linux distros will be supported at launch?
Fedora, Debian and ArchLinux will be supported from the start. We hope
to see support from other distros later. (Because of issues with newer
releases of Ubuntu and the ARM processor we are using, Ubuntu can’t
commit to support Raspberry Pi at the moment.) You will be able to
download distro images from us as soon as the Raspberry Pi is
released, and we will also be selling pre-loaded SD cards shortly
after release.

EDIT
It seems that since the launch of Raspberry Pi 2, Snappy Ubuntu Core can be run on RP2.
Thanks to a very successful collaboration between the Raspberry Pi Foundation and Canonical, the company behind Ubuntu, we are pleased to announce that Snappy Ubuntu Core is available for the Raspberry Pi 2, the latest Raspberry Pi family member.
However, it should be noted for the anxious that this is not a desktop version of Ubuntu.
