Here's my idea for a new Amiga:
Drop the hardware discussions, that is the past
A OS that supports many different types of hardware
A OS that is open source like Linux and freely distributable
A OS that is super lightweight, fast and efficient. The same OS (trimmed down from the desktop version) can be installed on mobile devices.
Support through emulation for classic Amiga software
Support through emulation for MAC and Windows software
I believe with the above, Amiga could have a future again.
