After a week of use, I was very pleased with the SqueezeBox. It sounds fantastic and even using my wireless and USB 1.1 external drive didn't deter the ease of use. However, I had my PowerBook returned to me, which is my main music library and iTunes host. I proceeded to set it up as the primary server for the device. The installation was fairly easy (finding the long forgotten firewall settings took the most time), but the performance was atrocious. I read in the forums on Slimdevice's site that the daily builds have some performance fixes. I downloaded the latest build and still had no luck getting it to reliably play for more than a song. I then switched off the AirPort and plugged in an Ethernet cable and since, have had no problems whatsoever. As it worked fine with my Windows laptop, I am inclined to think it a problem with the Mac.
