An iPad case with a built-in stereo

Not just a sleek, protective iPad case with a multi-crease, folding cover that offers better viewing angles than the Apple-issued one, Belkin's Thunderstorm's also the first super-portable, premium stereo system for said tablet that's so powerful, they've deemed it a "handheld home theater"

Sporting front-facing speakers specifically engineered by a high-end mobile audio company, it provides room-filling quality audio with deep bass for up to 10hrs on a single charge. It can also be set up via a dedicated app so that it auto-adjusts levels to a particular "soundscape" when you're gaming, watching videos, or just listening to music, which is good, since you don't want to annoy the people sitting near you on an airplane with an improper treble/bass balance.
