I'm currently running on a 12inch powerbook (1.5ghz, 1.25gb ram, 80gb HDD) but just lately I'm finding it to be slow and it's starting to bug me. Especially with all the web pages running flash/ajax killing my speed. So I'm thinking of buying a new Intel Mac at the end of the year/early next year (Maybe even wait for leopard). But I don't know weather to buy a Macbook (black) and sell the Powerbook or buy and iMac (20inch) and keep the powerbook for running around on? Can anyone give me some advice as to the pros / cons to either?
