Market share determines what platforms people choose to develop for. "Winning" and "losing" is why I don't recommend the Palm Pre to anyone. It matters, and all other things being equal, I want to own a phone that runs the "winning" platform.
I propose that you don't get 'winning' platforms, just 'losing' ones. (Windows aside, that is - I think that's an anomaly that hasn't been and won't be repeated.)
Arguing for any particular platform 'to lose', if it's not clearly already lost, is just baiting. Arguing for a platform 'to win', when it's already shown that it's not lost, is about the same.
Advising avoiding a platform that's lost is a different matter - I wouldn't recommend the Palm Pre, the Sega Dreamcast, or the Atari ST.
