Either it didn't matter or (Score 1)

Either it didn't matter or you weren't around when Apple switched from Motorola to IBM... The CPU won't matter so much as the OS and applications. I've got: wireless iBook and ThinkPad, dual G5, Mini -- all using the no-brainer Bonjour to share Internet connection, printers and files. Apple has made working in a PC-centric world bearable... and I don't imagine that will change anytime soon... Microsoft buys companies or puts them out of business... no innovation there. Apple innovates, which is why I will continue to buy and use their products, partially to support innovation which I benefit from.
