I'm still running several PC's (one for gaming and the others for Folding@Home and one laptop), but am working on making the rest of the transition. One of the limiting factors is the lack of support on Forums like this one. As helpful as everyone is around here, I would think that a Mac support forum would do quite well. Yes, it may be slow going in the beginning, but I think it would pick up rather quickly.
I actually have recently bought a Lenovo Core Duo laptop that I have been attempting to trade off for a Mac laptop or sell simply because I would rather have a Mac. I have two older Mac laptops, but they just aren't quite up to speed and are being sold off as well to help fund the hunt for a better Mac laptop.
A Mac section might very well help bring new people into this forum as well which would be good for everyone.
