SONOS pretty much has a market lock on multi unit wireless speakers. iTunes on a mac supports multiple airplay speakers, hopefully iOS support is coming. With the Beats acquisition I think it is time that apple comes out with a line of products that competes with SONOS. Having to buy a 100$ airport express for each pair of speakers gets a little annoying. Plus there is excess hardware that isn't needed for purely adding wireless functionality to speakers. Would you guys be interested in AirPlay speakers from apple? and just to be clear, the main advantage would be a multi room or multi speaker setup which rules out bluetooth. also sound quality is obviously better.
