I bought a Thinkpad specifically because they're built to be easy to upgrade and repair. They're aimed at corporations, so the IT managers value that ability. I've upgraded the RAM and installed an extra hard drive. I'm probably going to fix or replace the CD drive in the future, since someone damaged it and it only opens with the paperclip method now.

I have an AMD Framework laptop on preorder that I just can't wait to tinker with.

I believe that manufacturers ought to be responsible for disposal of their products. I bet that if companies had to take back and figure out what to do with their broken products, they would make them much easier to repair.
