First off, let me say that the little gizmo sounds great. Really, considering the size of the unit, when I hooked it up to my Apple iPhone, it was quite impressive the quality and volume of the audio.

It's also a very nicely designed unit, includes a little carrying bag, and is easily slipped into a sock or spare shoe in your luggage: Unless you are the world's tightest packer, I can't imagine that you couldn't slip an iSP100 into your luggage before a trip.

The speaker takes three AAA batteries -- oddly not included -- and the wire is attached to the bottom of the unit, so there's no worry about losing any pieces or parts. I like that feature and don't at all like speakers where the wire's a separate piece.

Pretty cool looking device, eh? For $34.99 it's a reasonable price for a portable speaker too, especially one that sounds this good.

Except there's a fundamental design flaw in the device, one that'll drive you crazy.

The problem? The on-off power switch is on the top edge of the device and there's no defeat switch, so it's far too easy to accidentally turn the device on while it's in the bag. Do that as you put it in your luggage and the batteries'll be dead by the time you land.

Not good. The workaround isn't too horrible (pop out a battery before you pack it) but it's unacceptable that you should have to do this to compensate for a design error.

If you can live with that, then I recommend the iSP100 in any of its many colors, but if that sounds like a pain, well, maybe they'll have a second generation of the unit available in the next few months.
