Sony's cup holder speaker forgets about car stereos

This is Sony's new portable speaker and iPod dock. It can either be used as a standard dock or the speaker can be removed and stuck in your car's cup holder. You know, just in case your car doesn't have a stereo of its own.
It's a neat idea, I guess, I just wonder how many people really need a standalone stereo for their car. Most new cars let you plug an iPod in, and older ones can play an iPodeither through a cassette adapter or FM transmitter.
But hey, this claims to have 360 degrees of sound distribution, so maybe it sounds better than the lousy speakers in low-end cars. I'm just trying to keep an open mind here.
