What you need is to give the avarage user an easy to use OS alternativ to Windows.
Mac is to expensive and Linux is not user friendly enough.

But with MOS you have a light, fast and easy too use system.
MOS only lacks some Software to be atractive enough for the avarage user that only needs the PC for the Internet,
Office, and some Audio/Video stuff.
They also want a quiet system that didn't need to be installed from scratch every half year.
Show the people what MOS and Efika means. "It is fast, easy to use and quiet."

On the other hand you need Developers, how do you get them?
Give them some good tools(IDE) they allready knew from other Systems and good Docs and tutorials about how to code for MOS/Aros.
