iPhone Application Dev Using Flash CS5 - it's just that simple

It looks like the next version of Adobe Flash CS5 will have an easier workflow for creating iPhone applications.  Here is a video tutorial for a simple ball animation using the phone’s accelerometer: http://gotoandlearn.com/play?id=116.  It is interesting that there was no Objective-C in this tutorial.

What is also interesting to me is just how proprietary all of this is.  You need to have Adobe Flash CS5, it is possibly easier to work with on a Mac laptop, an account with Apple for iPhone application development, and an iPhone.  Which also requires that you use AT&T as your phone carrier.  You can develop and test just like Adobe Air, but for accelerometer testing, you probably need a phone.  He shows in the tutorial just how easy it is to use iTunes to deploy the application to the phone and see if it works.

So what is the cost to do all this assuming you don't have any of the tools?

MacBook Pro 13in: $1199
Apple iPhone 3GS 16GB: $199 with a two year AT&T contract
Adobe Flash CS5: (it isn't out yet, but based on CS4): $699 est.
Apple application account: $99 per year

Total Estimated Barrier to Entry: $2,196.
