Manufacturers and carriers are showing commendable restraint in avoiding totally bastardized, walled-garden versions of Android on their handsets (for the most part), but they're not avoiding it altogether -- take Sony Ericsson here, for instance. The company has announced that it's expanding the reach of its PlayNow app store to cover Android in concert with its launch of the X10, which presumably means that users will be juggling a minimum of two sources for third-party wares on this thing. Long-term, this kind of needless fragmentation seems like one of the greatest threats to Android's ability to become and remain a heavyweight player in the smartphone ring -- but then again, what do we know? It's not like these guys haven't already figured out how to dominate before with UIQ... ah, wait. Anyhoo, yeah, back to the topic at hand: devs are now invited to submit their Android apps for inclusion in the PlayNow store, so hey, you may as well -- the phone's looking to be a hottie, so it can't hurt to have your stuff featured on there, we figure.
