It's getting silly now
Good grief! The latest in a long line of useless ipod accessories is an idog.
OnRobo: idog
Apparently, you plug your ipod into its leg and the sound comes out through a speaker. Then the LEDs on its face light up to 'express emotion'. Just like a real dog, then.
Just avoid songs like "Play Dead", "Roll Over Beethoven", and the soundtrack to "Faster Pussycat! Kill! Kill!"
