I am in the same boat as you. I run a T400 from 2009. It would have been fairly high end for the time (2.4Ghz Core 2 Duo, 4GB RAM) and I think that is why it has held up so well.

As now, there is a very wide performance profile for machines around then. From sub Ghz Celerons up to 3Ghz plus dual core things.
