Is NetBSD really running on PDAs? I don't know any BSD for PDA
project. I'm running familiar linux on Compaq iPAQ and it's quite good
and supports many PDAs (iPAQ, Zaurus, a few Toshibas and Dells). I
have no idea why people port Linux to the PDA instead of NetBSD, but
it seems everybody uses Linux for mobile devices.

I doubt there is any licensing problem with the a GPLed Linux kernel,
as binary closed source kernel modules could be used. Examples are
Nvidia drivers and the commercial OSS (sound card) drivers.

I don't see a real disadvantage with using linux, although I'm not the
one who thinks Linux is always the best solution for everything.

How much performance would we lose with the JIT? For me it sounds like
it would be the best solution.
