Remember the Bone HORN speaker amplifier for the iPhone? Now they have a version for the iPad 2. The HORN is a silicone adapter that fits on the bottom of the iPad 2 and uses acoustic science to amplify the sound from the built-in speakers by 15 decibels without using any additional battery power. There's even a fold out prop on the back that you can use to orient your iPad in either portrait or landscape position. The Bone HORN stand is available in 3 colors (Black, Grey and Pink) and can be purchased from CyberGuys for $29.95.
