I see no reason why a phone meant for productivity can't also be used for entertainment (see: CorePlayer, the games that ARE out for Windows Mobile, and even the camera built into most PPC devices these days). I also don't see why a phone meant for entertainment can't also be used for productivity.

The iPhone and Windows Mobile devices are both the same basic thing: a pocket-sized computer with a phone built in. Their capabilities are currently different, but that doesn't mean that they won't, can't or shouldn't overlap. The iPhone should mature into a device with capabilities similar to PPC devices, and PPC devices/Windows Mobile should mature into something with capabilities similar to the iPhone.
