I'm curious about the consistency of applications written for WebOS. Just to name a few:
* Is there a standard set of controls?
* Will an app built as a "local app" work on the web?
* Do you have to use HTML 5 to build mobile sites for WebOS?
* Does WebOS's browser support meta viewport width/height and will it generally be compatible with MobileSafari?
* Does everyone have to write a home brewed drag and drop or are these gestures included for free?
* No Accelerometer.
I personally don't see the Apple App store hurting for submissions because you have to know Objective-C. I would also rather spend my time using Objective-c controls than writing JavaScript controls to use.
