I was waiting to see what happened at macworld, before spending any money to upgrade my 12" powerbook. Now Macworld has come and the ultra portable has a horrible glossy screen so I will not be buying it. I don't want to have to go to a PC notebook, but it needs to be upgraded. I know I can't do anything about the processor which is at 1.33Ghz. I plan to max the RAM does anyone have recommendations on where I can get a 1GB stick cheapest? Also what is the largest HD that I can stick in here? And are there any other upgrades that I can do that I haven't thought about?
