Apple's App Store, with its millions of downloads, is clearly a hit with consumers. But with developers? Not so much. Like a dashing hero to a scorned mistress, Google's Andy Rubin is pledging a different, more loving and respectful relationship with those who would fill his company's Android Market with selections -- and his pockets with royalties. He indicates that the Market will enable free downloadable trials, something that Apple is stubbornly refusing to add, and that those downloads would not be subject to any arbitrary bandwidth caps. Meanwhile, T-Mobile at least will be levying a $2/month fee on developers of free apps expected to use more than the (somewhat arbitrary) amount of 15MB of data per user per month, though how they'll be keeping track of that data outside of their own content stack is unclear -- our guess is that they can't.
