On phones, webOS was pretty slow and not all that smooth, until the Pre 2 came into existence with about twice the processing power and webOS 2. Unfortunately, webOS was already floundering at this point and Verizon was the only U.S. carrier to launch the Pre 2, so very few people ever got to experience it. There was the HP Veer on AT&T as well, but that was quite the niche offering. Despite webOS being around for two years before the launch of the HP TouchPad, the device was less refined because so much of webOS 3 was new. It was the first webOS device without a hardware keyboard, for instance. It was also the first without a gesture area, the first with that new notification system, etc.
