The last time I had an up-to-date ish computer, I spent £1250 on a sony laptop (my eeepcs don't count as they were low spec compared with a laptop anyway). Athelon 1400 processor, 256 MB RAM, 20Gb hd, 14" 4:3 screen, XP home.
I deserve something not second hand for once.
Thanks for everyone who helped me choose. I'm waiting for the paypal address to pay and then he's gonna order the bits. He's also gonna transfer my 4 port USB 2.0 card to the new PC.
