I just got my new MacBook in. I gave my sister my 12" ibook (1.2 ghz g4). It's a real beauty but its noticeably slower. Granted I got the lowest version, but it still seems like it should be an upgrade from my previous 'book. Applications launch really slow and it's very choppy and loves the beach ball. Could this be something as easy as a RAM issue? My old one was snappy, and that's what I'm looking for. (This is a 1.8 duo with 512 ram). Any ideas?
