The Arduino A000065 shield allows for connectivity to a wireless module such as an Xbee, plus there is additional space on the board between the headers for prototyping.
The Wireless SD shield allows an Arduino board to communicate wirelessly using a wireless module. It is based on the Xbee modules from Digi, but can use any module with the same footprint. The module can communicate up to 100 feet indoors or 300 feet outdoors (with line-of-sight). It can be used as a serial/usb replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options. The shields breaks out each of the Xbee's pins to a through-hole solder pad.
Included on board is a SD card slot. When using the SD Library to access the card, Pin 4 is CS and cannot be used otherwise. SPI also relies on pins 11, 12, and 13 for communication.
The Wireless SD shield has an onboard switch labelled Micro and USB. This determine how the Xbee's serial communication connects to the serial communication between the microcontroller (ATmega8 or ATmega168) and USB-to-serial chip on the Arduino board.
