Macs, in my humble opinion do suck. I have never liked the interface that seems to be a prevelent style in Macintosh.

Oh well though, they do process quickly and are great for CGI, CAD, and the like. But I think fall short to the PC market in affordablity, applicaion versatility, and of course who make games for Macs these days.

I would say keep Mac alive for the sheer reason to keep Microsoft at bay with SOME kind of competition however small.
