Advice, new computer

[jack]

My laptop is getting flakier and I think I need a replacement. Anything fairly modern will probably do, I want to use it primarily as a home machine, but that I can easily move it around the sitting room when I need. I'd like to be able to run games from the last few years occasionally, but probably not the latest releases.

Has anyone (cjwatson?) bought a new computer recently, what did you get?
