Also, what companies would bother making hardware for AROS??
None.. But that is not just a negative thing. Aros team can actually pick any hardware that they want, be it x86, ppc or even port it to the classic amigas using old m68k or your pda.
AmigaOS on the other hand is locked to only one piece of hardware that is no longer in production.
How the hell is AROS going to continue in future with no funds coming in,
That is the wonders of open source.. The aros team does not expect to get paid. Though a donation here and there does not hurt.
when the Old AROS team desides to stop, and let others do it, how can we be assured that others will do it??
If it has users and enough support, then there will always be someone who will code just like with linux. But it needs the support from the amiga community for that to continue.
