I don't find most of the UI beautiful or elegant, most of it was too dark and reminded me of those first ugly mobile Linux GUIs , some of WebOS is quite well-designed, pretty, and usable, though.
The big issue for me is how long it took to load things, be they apps, websites, or search results. Whereas, the iPad 2 does everything just about instantaneously, it was a 3 second wait for anything to happen on the TouchPads. Those 3 second lags really add up on annoyance after a little while.
I wanted to believe, but in the end, it seems I was right.
