I don't really get the whole portable-cellphone-speaker thing. I mean, sure, I guess it's cool to have a speaker with you to play songs from your phone for your friends, but how often does that come up? Especially when said speaker is too small to have any real oomph but also too large to be convenient to tote around?
Well, that's not stopping Sony Ericsson from releasing the MS500, a round portable speaker that connects to your phone via Bluetooth to play your tunes wherever you are. It can dangle from any number of things with the included strap, and has 5 hours of battery life. I will never, ever buy one.
