Love one of the anonymous comments on there: "From one HP employee to another: THANK YOU for this awesome OS and OTA. The Touchpad, the Pre 3 ... such awesome products. I truly hope our new leadership will do the right thing and bring the platforms back."
It is an awesome OS except for one significant drawback: javascript. If not for the dependency on js these phones and tablets wouldn't lock-up hard so often or hang for several seconds after touching the screen more often than not. I know js fans will object but their single-threaded, interpreted language is the #2 source of Palm/HP's troubles.
The #1 Palm issue, however, is the hardware manufacturer/s. If Palm had been able to use the same CN fabs as Apple the Pre would be _big_. But they weren't and as a result the Pre/Pixi/Touchpad are larger than they could have been and, more significantly, the (Pre/Pixi) keyboards are the worst on any smartphone.
