I just switched from a 1st gen Palm Pre to my first iPhone 4S and I cannot agree more with this statement. webOS has a great UI, but it lost all the important battles (app ecosystem, quality hardware to run on, etc). iOS is now picking up a lot of webOS goodness (notifications) and the app ecosystem that Apple has is just... mindblowing. John Siracusa, in his Hypercritical podcast, made a great case for Amazon picking up webOS for use on their new tablets, but that horse has already left the stable with Android.
