Recently I've been using Appcelerator's Titanium to build my native desktop apps with html & jquery. Frustrated from the lack of updates and bugs, I decided I'd test out Air 2.0. Let me say, I'm extremely disappointed.
First off, this whole sandbox crap ticked me off and was a major factor for my reasoning to not pursue this product. Why would I use a product which limits my capabilities from achieving a native desktop app while they take away and decide what we can and cannot do. Yes, it can in some circumstances be a good thing, but it's annoying and kinda makes me feel like a kid governed by parental controls.
Secondly, this whole big red warning when the user installs the app is THE top reason why I think air is crap. Don't you want the users to be installing apps built with Air? Right now I've got the feeling you don't. Like stated before, you make me feel like a kid who can't be trusted, and the only way to be, is to fork out a grand to get code signed. Why would I do that? Every other Native language I can think of doesn't require this stupid little feature hold back. If I really wanted to write a virus, I'd do it in a better language.
I am extremely grateful you created this product since I can now feel satisified with Appcelerator.
