Kurt,
I look forward to hearing about your experience. I am more than likely going to be picking up a MB, but I'm going to wait until later in the year before I do it. I figure that VW12 (or 12.5) will have the bugs worked out and be optimized for the intel chip by that point.
If I had to buy right now, I'd probably go with the latest revision PB 15. It really is a decent machine, runs 11.5 wonderfully with 1GB of RAM. You know all of the current apps will work with it, and you will be current for at least 6 months. With the new MacBooks, I'm waiting on the revB, or even C, when the processor is truly unleashed and the other hardware components and applications are in sync.
One thing I wouldn't do is buy that Dell....
