This is cool. RVTec has developed a sled, called the Guyver, for the Palm m5xx series and the Sony Clie line of PalmOS PDAs. This sled lets you use PCMCIA cards, Type II to be exact. This will let you use wireless communications cards, such as WiFi and Bluetooth. The thing that really bugs me is that they just say “Sony Clie” and do not tell the series. My guess is that it is compatible with the N or S series, and not the T, NR, or SL/J series.
At least now that the last three of the mentioned series all use the same data connector, we may see more accessories for the line. I doubt we will see anything like the Guyver though.
