I think I agree with Lap Cat here. There's a place for cheap apps, but the problem comes for people developing productivity (or worse, vertical market) software that's going to sell "mere" thousands of copies, or tens of thousands at best, rather than hundreds of thousands or more. If you sell 10,000 copies at $50 a copy, you've grossed well over a quarter-million even subtracting Apple's 30% -- but if you're selling on a platform where it's hard to price anything over $5, you may have a problem, because one-tenth the price is probably not going to translate to ten times the sales.
