WebOS does and did feel incredibly pleasant to use.
They retained the mirror finish on the slide out behind the screen, which I think they used in ads for the original Pre to check makeup
The keyboard, I miss it so much and there were better ones than the Veer. I still have a Verizon Pre 3 that I would love to break out but I'm not sure how to get going now that all the firstboot servers are dead. Have to go through webOS-internals again
