What you have to understand is Amiga Inc is not interested in revitalizing the platform for the purpose of competing with the PC or even the Mac. Its sole purpose is for the users within the Amiga community. If it were actually a serious effort to create a business/home use machine, the project would have been completed years ago when Gateway owned everything.
The costs are due to the small production run and target user base.
Were it me running the show, I whole heartedly agree... A console system is the way to go. Just like the PS2 and it's predicessors, a game console with the ability to upgrade to a full-blown computer system. Then of course larger machines for game development and high-end use.
Sadly, no one of importance is interested in making anything out of the Amiga... Save of course those working on AROS.
