Just a few quick impressions of the SqueezeBox 3; I bought a SqueezeBox3 after reading about it in Stereophile.  It was easy to set up and I've not had any issues with the physical unit itself.  Occasionally the server software can have a few quirks here and there but overall its been very reliable.  I especially love the fact that you can control your SqueezeBox3 via the same web-browser-based interface used to administer the server.  I usually use my laptop to choose music on the SqueezeBox3 instead of the included remote control.  It's easier...
