The reason I haven't bought a Playbar wasn't because it was a bar. The Playbase is another high end home theater speaker in a different form. I was really hoping Sonos would create a Playbase in the $350 range. One that would be suitable for bedrooms or apartments. Now you have to choose between two very expensive Sonos solutions or a suitable soundbase from someone else that is not part of your Sonos system. If you want Sonos in that room you would then have to buy a separate (and redundant) speaker.
Please Sonos, have some empathy for your enthusiasts that can't or won't plunk down $700 for a TV speaker.
