Amiga proved in 1985 that you CAN launch a new platform
That was in 1985, before there was a need for all the browser and players.
The was a high amount (compared to other systems of that time) of money
invested in the Amiga and the result was grounbreaking HW and a
promising OS. Still the company that developed it went bust before they
could sell one single maschine.
The AOne (and Pegasos) are NOT groundbreaking in HW and the OS won't
make many heads move outside the "community".
This won't change until you invest 100s of million of $ to compete with the
likes of NVidia or ATI.
After that you would have HW that was up with TODAYS competition, but still
no "killer-apps" and no top-notch exclusie games to gain some consumer
interest. NVidia/ATI/?? won't sleep during the time of development and
definitly not afterwards. While your chips are restricted to one systems,
theirs run on all the others securing them the funds for continous developing.
Does Mr Citizen know what "PC compatibility" means? Hell no! His kids want a computer and here's a way he can get into computing without paying an arm and a leg.
The first thing that "Mr Citizen" will ask the salesman is if this no
computer can run all the available learnig-SW for his kids, if it can view the
latest web-pages, and if his kids can use the knowledge they will get on
this system in their further lifes.
