And this is also why web apps suck. Because AJAX, is also a cross-platform programming environment, and has exactly the same problems of inconsistency, slowness. And total lack of optimisation for the device. ie, touchscreen vs mouse.
I couldn't have said it better myself:
"AIR, like the cross-platform widget toolkits and application frameworks that came before it, is the gray mystery meat of client-side software. It gets the job done, but it's hard to stomach. For anyone who used a computer in the 1990s, AIR probably brings back scarring memories of Java apps: slow, ugly, inconsistent, awkward."
