Gameloft is a big name in mobile app development, so when they have something to say about developing for Android, it may be worth a listen. According to Gameloft, their iPhone apps sales outpaces Android app sales 400 to 1. Consequently, they have chosen to scale back on Android app development. From Gameloft:

We have significantly cut our investment in Android platform, just like … many others. [The Android Market] is not as neatly done as on the iPhone. Google has not been very good to entice customers to actually buy products. On Android nobody is making significant revenue.

Gameloft may have some good points. When compared to the polished experience on iTunes, the Android Market is far less exciting and enticing. Hopefully as more Android handsets hit the market, Android app development and sales will both prosper.
