Can you expand on your Titanium Android comment? I am about to embark on building an android app, and was leaning toward using Titanium, so would appreciate hearing about any roadblocks I might encounter.

I think you can't use native menus right now: http://developer.appcelerator.com/question/9731/android-bott...

Not sure about back button too. I'm sure it's all in flux.

From my experience, it's still incomplete. They aren't doing pretty basic things like "show controls on your movie player" etc.

I'd be happier if Titanium started up in under under five minutes. Something is seriously troubled in their linux version.
