I have the first Droid and I LOVE it. Get the new phone, it's at least a new phone and less likely to malfunction. I LOVE everything it can do. I can even check my online school site with it. I've got a few free games that the kids can play, memory , puzzle , and search and find type games. Great for long waits at the Drs office.
Another few cool apps
Keyring, know all those little discount cards you have on your key ring , you can scan them into your phone with the camera and throw them away. The only ones that don't work to be scanned from the phone screen are Best buy and the gas pumps at Kroger ( the angle is wrong for the pumps).
Shopsavvy, Scan an item's bar code and get prices for it at other stores around your location and online.
Shazam, ever wonder that that song is on that commercial or on the radio? just start up shazam , let it hear the song and it will identify it and pull up tour information for that artist.
Skype calls free from your phone , great for overseas calls.
Google Sky Map, "mom what's that star?" No problem, boot up google sky map and point it at the star, " nope sweetie , that's not a star that's mars"
search for planets and certain stars using it as well.
Last Fm internet radio for when the radio quits out on long trips.
Urbanspoon, this is great for when you don't know where you want to go out for dinner.
