This is very smart on Google's part. What Android seems to lack is polished apps (at least on the scale of the iPhone), and wooing specific developers could go a long way to remedying that.
Apple managed to get quantity, and with that the quality that you can often expect from the top 5% given enough quantity.
Google's much more surgical approach makes sense in that they can't realistically compete in quantity of apps any time soon, and thus have to specifically seek out quality to compete with Apple.
and if developer sentiment is an early indicator
Be careful: what you see on HN can be a very bad indicator of the real situation. All that was kind of blown out of proportion. There was kind of poll on HN asking iPhone developers how they feel about 3.3.1 and most of those who do develop for iPhone said more or less along the lines "I don't care much". The biggest outcry was probably from those who never did nor were going to develop for iPhone. At least they found some justification for that now.It's easy to get scared by rejection stores, but: App Store has close to 200 000 apps now. What are the real chances to get your app rejected?
