I'll happily run Linux on it until AOS4 comes out.
Which may be fine for a power user as yourself, but it doesn't compare to the Amiga A1200 experience. Plug-in, turn on.. boot up. You don't even need a hard drive (though its nicer with one). And software runs off floppy. Wouldn't a modern system with bootable CD-ROMs have similar functionality? :-D
For myself, I prefer to NOT touch Linux at all. I'm NO fan of Linux. (Of ALL the operating systems Linus had to copy.. he had to choose to make a UNIX clone when he really should have developed an AmigaOS clone. Oh well..)
Anyway, several years ago I preordered a Cyberstorm PPC accelerator card (Paid around $1500 for it & $400 for the 060 CPU).
It worked nicely, however, there was no software that supported the PPC, so I eventually sold it (then like 2 months after I sold it software for PPC appeared! Go figure!).
