Thanks for stiil showing interest in this Amiga OS like environnement

I think you can really make something big if you are able to release (for an handled device) something with some kind of good graphics acceleration and if we speak about morphOS, you NEED to have Java (like it or not it's a fact), an up to date Flash capability, of course a state of the art Web browser (without this one you'll go nowhere), an easy to use and shiny Mail client, a great media player (something really optimized for the hardware and MOS) AND a professsional SDK WITH a good IDE (something like Visual Studio is the must) the SDK / IDE HAS to be available on MOS, Windows and MacOS / Linux

All these things will make you able to compete (and survive)
