With Android finally in people's hands, Android Market was released to the wild and people were gettin' to downloadin'. However, there is one obvious exclusion right now and that is the support for paid apps. According to Google, Android Market won't receive paid applications until early Q1 2009.
Developers should also take interest in that it costs a one time $25 application fee to register the developer's authenticity and responsibility. After that, the apps that they develop are on the fast track to release. There is no further validation or approval needed.
Google also noted that they won't be making a profit off of Android Market. Instead, they'll use the 70/30 split (70% of paid apps to developer, 30% to Google) to finance the upkeep of Android Market.
