My powerbook has died, and I need a new mac. I've found a 2nd hand MBP (2ghz with 256VRAM) for less than half the cost of a new macbookpro. Price of 2nd hand mbp is R10,000 (approx $1000) New mbp is R25,000 (approx $2500) Is it worth it? Is the speed difference between 2ghz and 2.4 really that noticeable? I like the fact its got a the 256 gfx and not the standard 128mb one. My other option is to go for a new 20inch iMac (approx cost $1500) What i really want to know is this model too old? Advice please.
