This is actually an extremely interesting technical problem though, isn't it? Given all the computational power Google has, I'm sure they could dedicate one emulator per new submission, and run continuous checks on the app without ever resorting to manually reviewing the apps the way that Apple does. My guess is that the Android team is the most overworked team inside Google, and they're struggling to keep up with their own growth, so they've had to deprioritize some things like the market, and focus on simply getting Honeycomb out of the door. By my theory, the Market should see some real improvements in the coming months. We'll see, I guess.
