I have a problem with the A1200, although I like the idea of AGA and occasionally play AGA games, I always go back to my A500 running WB 1.3 because it is more nostalgic for me.
I mean, that's what matters.
For me, I could sneeze and AGA would vanish and I'd never even notice. My SNES blows it away from a game machine perspective. WB 1.3 does virtually everything I need it to do, and it does it very well - whether it be games, software applications, hardware needs - everything. There are some nice-to-haves with later OSes and chipsets, but not enough to get me to go there as those whistles and bells usually mean compromising compatibility. I've nothing against it, either, I just prefer the older machines and experiences. So I totally hear ya. And I know several folks who grew up on the 1200 as their first Amiga and understand their perspective, too. There's no singular "right path" - just yours.
So I bought into the keycap program (2 years ago? Man, it's been a while) and don't even own a A1200 anymore.
From the Kickstarter:
The fullset is compatible with ALL Amiga classic keyboards.
EXCEPT for the A1000 and some early versions of A2000 or A500 not using Mitsumi Hybrid Switches.
I mean, that's probably
going to kick me out even though I bought a set. I only use the A1000 and A2000 today. I do have 2 A2000 keyboards, but I've no idea what kind of switches they use. Maybe they'll work after all I but won't really know until the keycaps finally arrive.
If I had only one all-in-one to choose, though, it would be the 500 for me. It just works with the software I want to use.
