I have had a 17" powerbook 1.33, using PSCS, for a while now and it has been great for everything except recognizing the CF card reader when it is inserted, pretty slow there. Most Photoshop tasks show virtualy instant results. I have just purchased a 1.67 powerbook (the older one goes to the new college kid) and noticed right away that the new CS2 is much slower at every task than the older machine. I am very disapointed at this slowdown and wondered if anyone else has noticed the same.
