The review times have gotten better and overall the process of going from "New Project..." to "Ready for Sale" is much smoother than it was 10 years ago when I made my first iPhone OS app.

But the market is pretty hard to get into. You can add real value with a well-executed unique idea (like we did with Bubble Maker, look it up) but unless you're a big name or an established player, there just seems to be no chance of getting your foot in the door.
