Because using a web framework that only works on mobile is not truly platform agnostic. It may be platform agnostic in that it works on multiple different mobile platforms, but a mobile first web framework is not truly platform agnostic as it doesn't work for the desktop web.
So it's more agnostic for mobile development than the native mobile development you're clamoring for?
Also it's really not a big step for them to polish the desktop experience. They just released 0.2.0, give it time and I really do think that it's going to be a great platform for both mobile and desktop.
It's more agnostic than true native development but less agnostic than a lot of other frameworks out there.
And I agree that it is an early release and that they have room to improve on the desktop experience. I was just commentating on the current state of things.
All other things aside I think it looks like a cool framework with lots of potential.
