Lots of people think that Apple's big mistake was not porting the MacOS to the Intel platform and licensing it as a competitor to Windows. But one of the great things about Macs is that the hardware and software is designed by the same company, so I works together much better. Microsoft has gotten better about this recently, but they still are a long way from true "plug and play".
I have Macs at home on an Airport network, but I'm considering getting a PC because there are so many programs, espcially for kids, that are PC only. I'm especially disappionted that Apple hasn't done a better job convincing DVD makers to include Mac support to their PC-DVD features. Almost none do.
But I'm not going to give up my Mac. It's just so much cooler than any PC.
