I think it comes down to what do you really want? The future of MOS (IMHO) is the same as AOS currently. Which is unsure. We don't know if it will be actively continued or not. As far as the HW goes well the Pegasos is being produced currently. So it comes down to, do you want the name Amiga (just because it's a name), or do you want something that works and is upgradeable and currently being manufactured?
