An oft-asked question (in this forum, any way) goes something like this:
"I am a high-end user looking at a 12" PB. Will it work for my needs?"
A month or so ago, I asked the same question and thought my experiences
might help others.
My dual 2.0 G5 - which normally was being used 8hrs a day - just passed five
days without being used at all; all of my work being done by my new 12" PB.
Aside from speed and monitor size (I don't plug the PB into another monitor),
the PB has been a wonderful workhorse.
I've owned 15 Macs over the years and currently use 4. The 12" is by far the
best purchase in terms of cost/performance/utility.
Though I wouldn't use the PB 12" for movie editing or DVD composition, it's
just fine for Illustrator, Photoshop and Keynote/Powerpoint.
