For me it's more about the software and not about the power of a machine. So back in the days it would be nice if the CD32 had more power but today it doesen't matter. If I wana play old games on CD32, ok I am fine with the stock hardware. If I would make different things then gaming on old Aimiga Hardware, I use my Amiga 1200. And if I wana have new software I use my PC or other modern hardware.
I love Retro but I don't really looking for new technology on old machines (only exception is new hardware that can save old hardware).
