I am thinking of buying a Powerbook G4 with 1.5 ghz and 1.25 gb of RAM. What changes can I make that would maximize its performance? I was thinking of: - installing a 64 gb SSD. Would this make things snappier, what's the best place to buy? - upgrading the RAM. Is 1.2 gb the most available? - replace the battery - what's the best place to buy a new battery? Thanks!
