Truly wireless - Battery Powered PLAY unit

One more vote for a battery powered speaker. Would be nice to have a speaker I can take to parts of the house I'm not always in. I'm a big fan of the portable bluetooth speakers - so something small and portable. Bonus would be if it could play outside the system - on it's own - outside the house so I can take it to work or jobsites.

I REALLY want a portable streaming audio unit & I've been looking at the Bose (!) Soundtouch portable - $400 - but...

(a) it doesn't work with a NAS drive (yet)

(b) it's battery life is only 2.5 hours

(c) the battery is integrated into the unit

My wish list would be...

(1) Multiple connectivity - wi-fi for when I'm at home or in the garden, bluetooth when I'm away or out of wi-fi range, also preferably play mp3s straight off a usb flash drive & have a aux in phono or jack for total flexibility.

(2) Long Li-ion battery life - closer to that of a bluetooth speaker (8+ hours) &/or removable rechargeable battery so that you could take along a pre-charged spare that you could hot-swap. Just don't make the cost of spare batteries prohibitive!

(3) Charge on base unit at home & from (mini) USB on a laptop

(4) Max weight (incl battery) of 1.5kg

Please, Sonos, do it before someone else does...and do it better!

Would buy something like this today. Any update?

SONOS, SONOOOOOSSS, WHERE ARE YOU???  PLEASE ALERT CUSTOMER RELATIONS DEPT..... !!!   There is an obvious need for a rechargeable, portable speaker with 10-12 hours battery life to add to your range.... please reply????!!!!!   

Me too. I would love a sonos I could take to the bathroom or just outside the back door when sitting in the garden.

I am planing to buy any portable speaker to take outdoor . If Sonos could only confirm this speaker i will gladly wait so could ad a unit to my existing Sonos home system. Please make this happen.

I would definitely buy a rechargeable battery powered Sonos unit, happily accepting a compromise on volume / power for the benefit of 3-4 hours occasional but convenient garden use synced up to my existing Sonos system.

We too would definitely buy one, or maybe 2, of a good sound quality/reasonable output, say Play 3 standard, rechargeable player that could be taken out to the garden areas we are working on.  We currently have 6 zones, including outdoor speakers on our pool terrace and at the moment have to rack up the outdoor zones to get any sound to the garden areas.  We have bridges in the outbuildings so coverage is not an issue.  Not interested in having an ipod or similar dock, (although I can see these might be a selling plus) just access to the music library and radio as the rest of our Sonos system

Plus one here. in the UK we cannot have mains power in a bathroom. I would certainly take a Play 1 in there if I was able to lift the handle on top, to unlock it from its base, where inductive charging has charged the battery for my bathtime listening. If it can be done for a toothbrush.....

Will competition from Aether's Cone finally get Sonos to give us a battery powered Play? http://www.aether.com/details
