Here's an interesting use of PDAs + iPods to become a better bird watcher... Makes sense if you can quickly cycle through a ton of photos and songs when you're out in the field...

Birdwatchers have long headed into the woods with little more equipment than binoculars and a notebook. But when Laura Erickson sets out on a birding trip, she now brings along two digital cameras, a Palm device with a bird-species database and an iPod loaded with bird songs.

"I used to be a very low-tech person," says Ms. Erickson, a 55-year-old ornithologist in Duluth, Minn. "It's become such a high-tech kind of thing, with so many people carrying so much equipment now."
