First, wait and see what happens next week on Apple’s web site. Lots of new upgrades may be announced, so wait until next Monday night before deciding anything for certain.
But even if the Macbook Pros DON’T change I would still suggest one. I have been very, very happy with mine. As long as you get the newest version of Final Cut (5.1) then you will have the universal version of that. If you have an older one, search the Apple website for “crossgrade Final Cut.” It’s fairly cheap to upgrade right now. Pretty much all Apple software is Universal now.
All Microsoft and Adobe products are not yet universal. The new versions of their stuff is probably coming out in 2007 and will be new versions, in other words: paid upgrades.
But the current versions will run just fine on a Macbook Pro. Yes, they suffer a slight speed-hit because of it, but a Macbook will be MUCH faster than your old iBook is. So even if Photoshop is slower than it could be, it’s still faster than it was on your old machine. I use Photoshop on mine and it’s perfectly usable. I’m looking forward to when I can upgrade it and get a speed boost, but at the moment I have no trouble using it at all.
