Why is Tizen even mentioned? Right now it is NOTHING beyond a web site. They're the true vaporware!
Here's why WebOS had me excited:
It represented a forward-thinking ideal in user interfacing. It was HTML5-based. It used standard linux libraries (such as the ubiquitously mentioned libpurple). It had a logical user interface which was both coherent and universal.
Android may be pretty on the surface in some regards, but it is ugly on the back end. It is proprietary in many ways!
I want WebOS to succeed because it is the most elegant solution.
DEATH TO DALVIK!
