It was really ahead of its time and most of its major metaphors can be found in the surviving mobile OSes. Just wish the web-centric development model survived as well.
I have WebOS on my LG TV now. It sucks.
I really enjoyed the HP Touchpad with WeBOS but there were some rendering issues with it that I noticed when going to certain websites. My father in law got me one during the flash sale as he worked at OfficeMax Corporate at the time and had access. For ~$60 it wasn't too bad at all.
No sooner did I type that sentence than I decided to google it, WebOS has been rebranded to LuneOS, which sits on top of Android.
