To be honest, I can only come up with a few possibilities that COULD revive Amiga, and the chicken must come before the egg of software.
The Mini/Micro-itx plays a part in this.
There are many people left who have no internet access that want it but are afraid of computers. Amiga could market a STB or low end machine that is bundled with a monitor. Unlike other internet appliances, this machine should not be tied to a particular service IE: MSN or AOL. The user would be free to choose a local provider that the retailer could recommend. The machine is then cofigured at point of sale to be the customers internet solution, be it broadband or dial-up.
This would have to be a low cost product to get numbers into use.
The machine could be billed as an expandible system that could be used for other purposes as the user becomes more advanced. This would get interest from the budget minded set that needs an internet machine for the kids and would like to learn to do their taxes on it...etc.
As machines are sold, the software will come... maybe slowly at first, but it could snowball...then again, this may stand a snowball's chance...
I know... some people are thinking that this solution already exists, but it really does not, or at least not in widespread distribution.
Price is paramount and it may be necessary to run extremely low margins for some time.
Just my two cents.
