I don't think they're perfect, but I don't know how you'd make them better using current technology. Only thing that comes to mind is a foldability to make them more pocketable I guess. Ergonomic as phones? I would imagine the actual "phone" part is now a secondary feature at best to most users. Annoying for web browsing compared to laptops? Yes, but it's also pocketable while a laptop is not. You can't exactly whip out a laptop to browse the web while standing in line at the DMV. Not satisfying to use to control physical devices? I agree, but the touch screen UI lets you able to control multiple physical devices instead of having a separate physical remote for every device. Again, with the caveat of using available current technology, I don't see how you can make smartphones better than they are now. It's a jack of all trades, master of none device.
