I"m interested in a bluetooth speaker for use around the house and outside. It has to be battery powered and portable. Doesn't need to be ultra small. In fact, I'd prefer something a little larger to get better sound. Units I've been reading about include: Jawbone JAMBOX Soundmatters foxLv2 Monster Clarity HD Altec Lansing Inmotion Soundblade Creative D100 It seems like I'll get better sound from something about the size of the Creative D100. Anyone have experience with this unit? Any other options, perhaps something a little higher end? Again, it has to be battery operated. I was thinking about the iHome iW1 but my understanding is airplay requires a wifi network. I'd like something that I can use while car camping or at the park. So must be battery powered and have good sound projection. Any suggestions or advice appreciated.
