The 10^6$ question is whether Richard Stallman[1] would use this?
OT, but an amusing line from that page:
> I never pay for anything on the Web. Anything on the net that requires payment, I don't do.
Or more succintly:
> Out, out, damned Spotify! Flick off, Netflix!
I have a non-core boot X61s Lenovo that happens to have an ath5k wifi card built in (there are various different configurations of the X61s so don't assume they will all have an Atheros card) and I have not seen a Linux it could not run. OpenBSD works fine, so I assume that other BSDs would.
A little underpowered by today's standards, and tends to get warm if you are compiling a lot of stuff or other processor intensive applications, but fine for what I do most days.
