It wasn’t so long ago, when if I said: I’m a developer, people would instantly think that I must be programming applications for PC’s. Today however, PC’s are only one part of the market. Macs, linux distributions, mobile devices based on iOS, Android and Symbian. There are too many out there and developers usually feel that they have to pick one and hold tight to it, which is extremely dangerous as it might not be as popular 2 years later.
The Appcelerator Titanium SDK offers us a sense of security as it allows us to build applications for a variety of platforms from the same codebase. Meaning that you will not have to re-write the whole application from the ground up if you would like to release it on the Android as well as the iOS.
