Which would be better (performance and development time) for me if I'm creating an desktop application using HTML/CSS/JS?
Is AIR more efficient at Flex and ActionScript than HTML/JS?
I've played with Titanium for a bit, but packaged app is more than 30MB, which is more than the AIR runtime + app. Is it alway that big or am I missing something?
Titanium ships with the entire runtime, adobe air does not. A person doesn't need "Titanium Desktop" installed to run your application.
I prefer titanium over adobe air, even though adobe air may be mature software for the following reasons:
It seems a restrictive, sandboxes and such.
It does not have bleeding edge web technologies, it seems as though adobe air hasn't updated their webkit even since the last version.
It does not require a user to install another application to get an application.
