FWIW, PC Magazine has recent glowing reviews of Sonos ZP80 and the Olive Musica. Squeezebox doesn't even register on their radar screens. Other than a passing mention in a 2005 review of "Wireless Entertainment Networks", they don't appear to have written anything about Squeezebox since mid-2004, aka the Squeezebox 1 era.
