First of all, this isn't a wireless card. USB is a different animal. USB stands for Universal Serial Bus. It's just a
fast serial port. If you connect it to the Newton serial port then it can only go as fast as that. In practice, it will
be a little slower due to overhead during the conversion. It can never take advantage of USBs'
higher speed. Caveat - A complete rewrite of the low-level comms could provide the speed hike but that would require a
good chunk of NASA's budget to achieve. ;-)

Oh no? What about a type B USB connector? Now where does the mini-din go?

Fine. But the keyspan adaptor is not that unwieldy and it leaves the option of using the standard serial port for a
keyboard - something that is lost if the USB interface is moved inside.
