"I doubt that "big outfits" such as Microsoft would be the least interested in RISC OS, much less so to simply kill it off. It's not as if RO poses even a minimal threat to any of Microsoft's markets and the market share doesn't even show up on measurements in the UK, let alone the world. The only thing I see that MS and others might be interested in would be the font rendering technology and even that may not be worth much anymore."
Well this is exactly what happened to BeOS for $11M. Palm bought the OS for a few things but not for keeping it going. Yellowtab now have it but IMHO it is too late. Lets hopew the same does not apply to RiscOS.
