Following a rampage in the Apple Store, this is now surplus to requirements.
2.53Ghz Core 2 Duo / 250GB HDD / 4GB Ram
Great condition, with latest OSX Leopard, latest MS Office etc etc.
Looking at eBay £500 seems fair but no doubt there'll be a few of you who will go scouting around to see if you can get better prices and post them up here. I look forward to it.
Anyway, there's the price - if it turns out you clever lot can find a better one for the price, I'll give it to my mother.
