Ask HN: What Thinkpad should I get?

I run Maverick Meerkat on an IBM R51 and I'm thinking of getting a new laptop. I have looked into the X301 and the T410.

Having spoken to a couple of users of Maverick on the X301 (with the SSD), they have recommended the T410 with the i7 processor.

Do you have an i7 based Thinkpad or an x301 and you run Ubuntu on it? What have your experiences been?

What I'm looking for is something bombproof. The R51 has weathered a lot of abuse. How do the Lenovo builds stack up to the older IBM Thinkpads?

And if you have recommendations to non-Thinkpad laptops that fit the bill, do tell.
