I think it’s easy to forget the palm pre and webos because it wasn’t a competitor for very long, but to be blunt, it was the only decent competitor to the iPhone but in the 2008/2009 timeframe. Android was awful on launch, blackberry was completely behind, Microsoft had a plan that was decent but was too late. Palm really was the only real threat in the early days. They just didn’t have the money to iterate like apple (and Google).
