Scott,
Actually, the Squeezebox would work very well with the MAC (according to its specs). If I get one, I'll connect it by wireless to the computer.
One of my main reasons for avoiding the computer route is that our music would be stored on the house iMac, which will get used by my wife, me, and any eventual kids, as well as visiting family members. I can just envision myself sitting down in my listening room (when the new house gets built) with a glass of single malt scotch and relaxing to the Haydn Quartets, when the iMac gets rebooted, or my wireless stream gets invaded by the soundtrack of the latest computer game featuring death, destruction and encouragement to commit extreme violence. Only Joking.......but I like the idea of isolation from possible interruptions.
Of course, I could put a computer in the music room, but then there would be the whirring small fans in the background. The Olive sounds good, but at an expense for the models featuring large storage capacity.
Internet radio may be handy, although we tend to listen to NPR stations, which are still available by regular FM wireless.
Maybe I am bit of a luddite. I spend my working days dealing with the high tech in a DNA lab that I manage. We don't own cell phones either, although my wife and I do have our HAM radio licenses!
Thanks,
Charlie
