As you know Lenovo announced that they are going to support Linux, their first option seems to be Suse, but know at their blog they are asking which Linux the people want to be supported on a Thinkpad.

You can vote for your favorite distro supported by Lenovo at its blog.

Take a minute to vote for your favorite one, I hope the do take into account the community preferences, but that is not assured, or could be great that they with the help of the communities could support two or three distros instead of only one.
