You're planning some festivities you say? Not so much a party as a BASH? The dinky rechargeable battery dock in your room is not going to cut it. You need something so big and heavy it needs a retractable handle and wheels.
Aside from the size and weight of the driver itself, the Backyard Blaster comes housed in a rugged case much like a PA speaker and has a big 12-hour battery. In addition to your standard 30-pin iPod dock, the Backyard Blaster carries an aux input for Android users or other iPhone-less wretches. Oh, and if karaoke happens to be your thing -- why wouldn't it be? -- the Backyard Blaster comes equipped with a built-in microphone. [Ubergizmo]
