1. We need a new CPU, if it isn't remotely PPC compatible we have extra work to do but at the very least it has to be something like 3.2Ghz triple core 6 thread CPU by IBM sold to Microsoft for use in Xbox 360.
If you want to keep the Amiga alive as a niche-system, you will have to either rewrite the OS to a virtual machine that is popular enouch to remain widely unchanged for decades or use open source hardware that can be manufactured ad infimum. Everything else is but a temporary solution (see X1000 & MorphOS).
4. Massive investment/incentive to get Firefox or Chrome quality browser ported to our new OS as well as all CODECS for a media player and a conversion of Open Office to stick it to the Microsoft Office man.
Alternatively you could include WINE and just have native support plain HTML5, WebM and ODF.
5. All the above must be handled by ONE COMPANY, none of this tweedle dumb does minor OS updates and tweedle dee does some overpriced fantasy motherboard only using 1/2 cores of CPU to run that software.
I take it you have a grudge against the current state of AmigaOS4, but that won´t help. We will have ppl. working on Amiga when they have time, money and a passion about it. This is not about companies anymore. Your loyalty can be to an idea not a brand.
