I've heard so much about Macs here and in other places that I decided to check them out. I got a 17" PowerBook G4.
First impression...this is gonna be a long process. I am soooo Windows-centric in my thinking when on a pc it takes me forever to do the simplest tasks. They are easy enough on the Mac...just so different. Not being able to right-click is driving me nuts. (I haven't tried to add a mouse yet)
A few things I've noticed:
Many of the web pages out there don't like Safari much... I'll be trying others like FireFox or even (Yikes!) IE for Mac.
During initial setup I had to enter a lot more info then I would normally like. That is probably just basic Windows security paranoia.
It is fast. Especially considering what I thought to be a slow processor at 1.67GHZ. CS2 runs great. Since most of the books I have use Mac in the illustrations using them has become easier. I haven't connected my camera (20D) to it yet or tried to work with RAW images yet, but don't anticipate any problems.
I haven't used it enough to have any thoughts about reliability or stability.
I'll post more as I go, both for the benefit of dedicated pc users (a group I've long been a proud member of) and so that from time-to-time the Mac users can say I told you so! ;) I'm sure I'll also post a few questions over in the computer forum.
