I'm curious how this program compares with iOS vis-a-vis potnetial market size and average development cost.
The development dedicated for iOS is always costly: because you need to have a developer account and a MAC (I don't recommand the virtual machine)... with XDK, you can create your applications for several platforms, so I think that adopting it as a solution is very worthy ;)
>>...The development dedicated for iOS is always costly...
For example, DragonFire SDK for iPhone development on PC - $99 USD ( dragonfiresdk.com )
if its was a large scale market potential project. the development costs are nothing. But if you ar trying for a small scale than its too cost
