Many valid points there, couldnt agree more. As an everyday usable computer the Amiga surely outlived them all. Like you said, no other 'retro' platform still has decent hardware/software development, relatively modern operating system and such an active user community.
Don't know the details but I'd say RISCOS challenges Amiga on most or all of those.
An even better "retro" challenger is Haiku. It's a lot more modern, runs on far better hardware and while it's hard to get numbers of the user base the numbers of people downloading it were in the order of hundreds of thousands.
BTW Going by numbers of active forum users is a completely useless way of measuring popularity of an OS. e.g. Haiku has never had a forum based community so you'd get the impression it's quite small.
