Palm offerings in 2007, such as the Treo 755p or the Centro, could not compete hardware-wise with the original iPhone. The claim that these Palm phones were "easier to use" is hilarious to me, and probably hilarious to many others.
The first gen iPhone is not a smartphone by today's standards. No multitasking, no copy/paste, no centralized instant messaging, all things WebOS devices had on release.
Even the second generation of iPhones felt half baked by comparison.
Which just goes to illustrate my point, that they weren't technologically superior, just more committed.
Both Microsoft phones and WebOS have surviving communities today, and would have thriving communities if new devices were available.
Sadly, it takes more than two consecutive quarters to establish a platform.
This metric has very little to do with quality.
Pretty good for something that supposedly failed 12 years ago.
