Time to market can take longer with Brew than with Java ME because of Brew's rigorous certification requirements.

This certification process may be perceived as an advantage by established software developers because the difficulties associated with testing and development costs create a high cost of entry to developers with low budgets and little time, resulting in less market dilution.

Specifically, developers of casual games run less risk of having to compete with freeware workalikes developed and self-published by hobbyists.

However this comes as a cost to the end-user as there's less competition to develop the best solution for the cheapest price to the end user.
