Ofcourse it isn't crazy to do that.
You already gave an answer on your question in your post.
The only thing at the moment isn´t fully developed is the games-area. But just wait a while and it will be blooming (yes I'm very optimistic).
I've got a Pegasos, my trusty A1200 and a PS2 for games and I can do anything I want to do.
About swapping files between different OS's I don´t know, sorry. :-)
