Hi Stuart,
Thanks very much for the information! I'm surprised the Pi will compile
faster, outside of IO issues.
And the WLAN on the Pi with no antenna? that sounds a bit weak... I was
looking at getting an aluminum case that acts as a passive heatsink, but
my gut feeling is that would be contra-indicated for good wifi... I'll
follow up with the manufacturer to see what their feedback is.
Thanks again!
Cheers,
Steve W.
