@bobx3: I agree. The last time I was flying, I forgot my cell phone charger (actually, it was a new cell phone, and I didn't know until the third day of my trip that the phone with a USB jack won't actually charge from my computer's USB port (who knew?) So I picked up a travel charger at one of these kiosks. I also grabbed a pair of noise-canceling headphones - iPod earbuds can be painful at the volume necessary to compete with jet engines!

They're a great idea for the kind of stuff that's in them: chargers, PMP's, (although, what use is an iPod when you don't have a computer around to load stuff in to it?), pre-paid cell phones, and the like. The prices weren't over-inflated; they were pretty much MSRP. In fact, the gift shop nearby was selling headphones for more than the kiosk was charging.
