This has always been the problem, I think.
where there is a problem one needs to seek solution, where there is not, you will not even notice. so what?
Even back in 1992 Commodore will have found it hard to make people use the new OS 3.0 API - but of course now we take it for granted. Developing for OS 2.04 or even OS 1.3 is unheard of.
first of all they broke the backwards compatibility, which was a bad move and splitted the user base. you have had to user kickstart switches, and therefore people stuck to 1.3 and were hesistant about especially 2.x, where there is almost no software for and also 3.x which was introduced almost simultanously with aga machines. it was by any means wrong politics towards the users, and it didnt help the platform for sure. yet even at that point it didnt kill it definitely, because it was still alive. this kind of approach today is simply suicidal.
There comes a point when the people still using the obsolete APIs like OS 3.x have to move on to stay current - it's always been that way, and always will be. Of course the problem now is what do they move on to. To some it's OS 4, to others it's MorphOS, to others it's AROS.... but only ever supporting an ancient platform like OS 3 - even though it's the lowest common denominator, is such a low power platform that catering to that as a primary platform will hold back all the newer platforms.
it will hold them back from splitting any further, which under the given circumstances is a good thing, definitely. except one of them had so much own dynamics, that it was actually able to take off for the future on its own. alas there is no such option, lets not fool ourselves.
We need to push forward, otherwise we'll be forever stuck with apps that are made to run on a processor from nearly 25 years ago, and that's no way to stay current.
in fact this is the bigest and most used pool of software you have acces to, whatever amigalike system you are sworn to. if you desperately need to push forward at the cost of losing it, be my guest, just make your choice and dont complain later of no company.
It's a very difficult one to call, though, and I completely empathise with what you're saying - the "Classic" is the common factor with all of us - and it shouldn't be ignored... but I think it should be treated more as a legacy platform rather than the current target platform. If something runs well on low-spec hardware, make it for OS 3 - but don't hold back progress on our multi-GHz NG machines for the sake of a 20 year-old machine.
are you implying, we are holding you back? how? none of us has any say on which way to develop os4 software, its entirely up to os4 companies and fans. i refuse to be blamed about that.
There's no simple solution (as usual for the Amiga world....)
if there was, this wasnt be a problem to discuss. im sorry, but a simple demand to thrash your amiga into a bin and follow any of ng alternatives wont work any better as it did up till now. want a solution, then face it.
