Cool, cell phone charger

Here's a tiny item from hi-tech & cheaper than cell phone accessories I've seen. One AA battery in a lipstick-sized case for the low side of $30 with shipping. Not bad for battery hogging treo's, the camper, hiker, frequent flyer, campus or board meeting cell phone frequent caller..for iPods soon. See it here http://tinyurl.com/eo8sk I'm checking it out.
