I think this would be nice if the USB modem could be
pushed into the case.
It would also let you detact the modem either to use it
in your laptop or to use the space where it was for a
USB flash drive.
Unfortunately, there is some downsides with this approach:
a) new case design would be required
b) those USB modems tend to be power hungry
c) it would make the rf design very hard (shielding)
