Things are looking increasingly bad for Microsoft's Windows Mobile operating system, and they may be looking bad for Palm, too. As GigaOm notes: Like a desperate gambler down to his last few chips, Palm is ditching Windows Mobile and going all in with its own webOS. That will leave the Pre as Palm's big bet in the smartphone arena, and the company has said that the Pre now accounts for the vast majority of the smartphones that it sells (823,000 units in the most recent quarter, in line with analyst's expectations).
What's more notable to me, though, is that as the heavily fragmented world of operating systems for smartphones begins to whittle itself down to a few competitors, players that rely either entirely or partly on open source are making the best bets.
