I've been a big fan of the Danger Hiptop cell phone, and have made a decent wage writing games for it. But writing in Java hurts my pride, and when my third Hiptop in a row died a hardware death I decided it was time to rethink my choice of platform.
See, the Hiptop just doesn't seem to be going anywhere. After about four years now, their hardware has changed slightly: a two-directional wheel has replaced the one-directional one, and the screen resolution is better. The camera is maybe 1.6 megapixels instead of 1.0. Wow. But it still doesn't have anything more than rudimentary bluetooth, doesn't have any kind of GPS, its CPU-power-to-display-pixels ratio is *decreasing*, and its radio... god help me, but GPRS connectivity sucks even when it actually works. Four years, and they haven't done anything about some fundamental problems.
So I've swapped brands, and am now one of the herd playing with an iPhone. It's a new world, baby. Looking forward to picking up some Objective-C, learning some xCode, and capitalizing on the latest fad.
