It reeks of "don't care". It's clunky in places, everybody has to roll their own gui toolkit to make anything that looks halfway decent, performance isn't that great (maybe the devices are slow), crap is buried in long lists of settings, I can use a microSD card with it but it's pointless because I can't install anything to that card, restarting the device is a pain since I have to approve a dozen security policy dialogs that don't fit on the screen, typography is a disaster. I once accidentally his the wrong security setting when installing Opera on mine and I have no idea how to change it, after a year of poking around and a full system wipe. So now, every time I go to surf the web, I have to spend 5 minutes fighting past security authorizations.
All this was okay in 2000, but the devices haven't evolved one bit since then. I got mine new, just on the market, in '08 from my company. Really, even with a new OS, the devices need to get with the times. Buying WebOS would give them a halfway decent, well thought out OS, and force their hand with the crappy hardware.
