[ from the continuous-upgrades-please dept. ]
You will think I am crazy (or alternatively you already think that I am) however I am planning how I would sell and upgrade the Powerbook to a 1GHz model. Plan of attack goes something like selling the old one for 1700pounds and then buying a new one at a cost of 400 pounds more. In the process I acquire a gain in Power, better graphics, double hard disk, internal wireless and double the system memory. Did I mention a slot loading DVD writer? Not a hugely bad deal really.
I will never be truely satisfied 
Jon.
