Totally awesome, but there's a big problem. Most of the time when you're in need of translation of text you find like signs, it's because you're in another country. That means data is very expensive, because your fancy iphone is locked and roaming.

It's awesome, many people may download it, but it will get very little use. :-\ They should probably charge like $5 or $10 for it, make money on people WANTING to use it, not on them actually using it.

Unless i'm mistaken and it's doing the image processing all locally, in that case, they've got a smash hit.
