I have to say to not being too impressed with my 2ghz macbook w/1gb ramm. I was upgrading from a 1.33gz G4 PB with less ramm. The problem is I'm constantly running out of memory, so it seems. Apps often take ages to quit as though I haven't actually just press command-q, they just sit there for 5 seconds. This never used to happen on the PB. Not very happy atm, seeing the spinning wheel far too much.
