The StarCard isn't cheap, it uses a single chip modem, able to function at the low power of the PC-Card slot in the Zoomer.
9.6 or 14.4 PC-Card modems require much more power than the Zoomer can provide. In most cases, except for in an air port, when you find a jack to plug the modem into, you can normally find an electrical outlet- where a portable (small) modem connected to the Serial port will function well.
Leaving the PC-Card slot for the RAM card..
