I am looking at buying my first mac either an ibook or a powerbook. I do a lot of video work and will continue to use my desktop PC for anything labour intensive. I do need to run Photoshop, Final Cut, Aftereffects and Shake however but not push them too much or use them simultaneously. I'd love some advice from anyone who has run Final Cut or Shake on an ibook. Is it realistic? I realise that running these apps on a portable is going to be somewhat sluggish but a dual G5 tower is not practical for my purposes. I hope i can get away with an ibook as the powerbooks seem to be a bit overpriced for such an old product line. Thanks.
