What's Your Favorite Gadget?

I've mentioned it before. I love gadgets. My favorite is still my Iphone since it has so many uses. I make and take phone calls and photos. I surf the net, send and receive e-mails, listen to music, watch videos, get directions, play the ipod, read books, plus so much more.

What about you? What's your favorite gadget? Maybe it's a Kindle, a camera, a videorecorder, a Swiss army knife, a TV remote, a garage door opener, an electric can opener.

Please name it and tell us why you like it so much.
