- That's about the lot of it. Look at the reports of people who own
- both 28.8 Sportsters and 33.6 ones.

- Not the new model Sportsters (the PnP ones), although they may be
- based on the same source code.

- Well, FWIW when I had a PPI v.34 with an old firmware, it's
- performance was very similar to that of the Sportsters, also with an old
- firmware. Each had some strengths and weaknesses, but the PPI could
- definatly transfer data faster then the Sportster if they were connected
- at the same rate and not getting any signifcant amount of BERs. The
- Motorola Power I also used to have would also outperform the Sportster
- when using the 256 byte LAP-M packets.
