I read that it can run html5 web apps just like normal apps, even pin them to your home screen, that's pretty sweet. To me it sounds pretty cool and looks nice but kinda basic for a smart phone os.
Also, do we need another mobile OS? IOS, Android, WM, Bada (you'd all forgotten about that one hadn't you!?
), Mozilla's new OS, and now Ubuntu too, plus I'm pretty sure I've forgotten at least one. Lol.
