Forget webOS even Windows Phone OS itself is way ahead of androind and even iOS in terms of usability. But you are right. People have ignored it so far. All they want is android or iOS.
A growing number of people "want" Android today but your average customer had no idea what Android was when Android beat the pants off WebOS in 2009/2010. WebOS was a great OS stapled onto the biggest laughingstock of marketing and shoddy production quality in memory.
WP7 was late and less polished but also suffered from carriers-dont-push-it-itis.
