I found my old Palm Treo 700p PDA/cell phone in the garage yesterday, along with its charger and a wireless keyboard.

It was a big deal when I bought it in October, 2006, but it is positively primitive compared with today's smartphones.

I hooked up the USB charger and the battery still shows 100% more than 24 hours later. That made me confident enough to offer the whole bundle for sale on Ebay where the phones alone are going for about $15.
