I don't understand killing the whole format. There's not really anything else quite like it. My kids love having every song, artist, playlist, that's on our computer, available to them in their rooms and remote controllable from their iPod touchs. They both have the smaller, single speaker "radios". It's a nice little player, color screen to show artwork, it can stream radio stations from around the world and sounds decent enough for 8 & 12 year olds. I will continue to use the "boom" as our alarm clock/radio in our bedroom, as well as a second one for portable music on the patio, deck or in the garage. Hopefully they stay functional for years to come. Or until someone comes up with a better system.
Actually, Sonos does all of this, only better. Sonos has "Play" devices that do the same thing as the Squeezebox radios and can be used as an alarm clock. The Sonos Play devices sound much better than the Squeezebox radios or boom. The Sonos "Connect" device can be used to connect to an audio system, same as the SBT. I used Squeezebox devices for years (had a radio and still have a classic and a SBT), but have switched to Sonos recently. Sonos is a much better interface that Squeezebox and and a much better "whole house" option. There are only two downsides to Sonos compared to Squeezebox. One, the devices are slightly more expensive and, two, they do not work with high rez files. If you don't need the high rez capability, then Sonos is the Cat's Meow.
I think there are some modders that will mod the Connect device to accept 24/96, but all my music is 16/44, so I haven't looked into it.
