The Fuji X100s goes on a long trip

The 16GB limit is because the Intel CPUs Apple uses cannot address more than 16GB memory. They could have used more power hungry ones, but then the running time on battery would have tanked. If you want to complain to anyone about that, then you should complain to Intel for completely not following their road map (whatever problems they had).
