Maybe in the US the Amiga wasn't maintream, but in Europe the Amiga was mainstream for home users. People either had a console to play games only, or an Amiga to play games on, do some work on, and even kids learned on it..
As for the name, many people have fond memories of the Amiga (500 era, and early AGA period, before the PC booming and C='s demise) and also rember the ease of use and power.. If anything, the abilty to just "turn off" the power and not having to shut down is for some a real +

.
Whether or not OS4 or MOS will survive, who knows.. The targeted markets aren't just home users, more Kiosks and controller type stuff, not Office PC types... Maye Hyperion / Genesi should show their OS to Nasa, they could be intersted in a stable / fast booting OS (Note; not the current hardware).. This won't make them mainstream, but at least keeps the money comming to further develop the OSes.
As for Aros.. As long as the main developers love to code for it, it will survive... After all, they are not in it for the money, but for the love of it... :-D
