I am planning on upgrading the with a core 2 duo or pentium m (about 2ghz) and the 40gb hdd with ssd (I know IDE SSDs are quite slow but the current HDD is making squeaking noises and is on it's last legs, like hanging on a thread, but made of nylon), both of which come to around £40, same price as the laptop funnily! If I have to deal with a Pentium M, thats ok and don't tell me "It's not worth it" or "It's very difficult" as I have done this before on my nans laptop (same cpu socket and everything) and I'm bored.
