Hi all Have been a reader of macrumors for a while and been the proud owner of a 15 inch powerbook 1.5ghz with 1gig ram since its release. Have watched the move to intel with interest and wondered whether now would be the right time to make the move? Am interested in the macbook for portability reasons, to be honest, wouldn't use the full capability of a pro as use mail, itunes, safari/firefox etc. though I do use aperture and photoshop from time to time. Wondered what everyone's experiences were in terms of speed jump between a 1.5 ghz powerbook and the macbook? Don't worry, won't start a debate on the matte/gloss screen debate! Thanks for your help in advance!
