Hi, I was playing around with the 1.25 ghz powerbook right next to the 1.6 ghz powermac g5, and didn't notice too much of a performance difference in Photoshop or Garageband or Flash or finder apps. What would be the huge advantage for waiting 9 months till the g5 powerbooks come out if they won't likely even run at a much higher bus speed like the tower processors? i can't imagine the 1.5 ghz being more than 10-20% slower than a 1.6 ghz g5. I don't need a powerbook immediately, but I'm thinking of getting the new 1.5 15" superdrive next week. Is this 'book going to hold its worth for long, or is Apple going to concentrate on 64 bit configs. and leave the g4 crowd in the dust? By the way, I'm using Pro tools and photoshop primarily...no video editing (although I will get the 128 MB video upgrade). I swear to God this is one of my last powerbook posts...I want to make the right decision .
