I get that a lot of people like WebOS, but as a developer it seems like the worst POSSIBLE thing that could happen is for a third mobile OS to actually get traction. Back in the days when Palm ruled the PDA market, things were good, but they're hanging out in fourth or fifth place these days. Regardless of merit of their respective UIs, the absolute best thing that could happen to the mobile space is if one completely open mobile OS became completely dominant. And pretty much the only reasonable contender for that role is Android.
