The question here (of course) is whether it's really not such a great bargain compared to a much cheaper Windows laptop modified like Gary's (which certainly won't sound worse, and perhaps noticeably better). I'm reading and typing on an iMac BTW.
I use the computer. And it was already paid for, so a pretty good bargain. But your point is well-taken. A $350 Windows laptop can serve the same musical purpose.
