The Zodiac 1 contains 32 MB of RAM with 20 MB available for storage and application memory. The Zodiac 2 contains 128 MB of RAM with 116 MB available. Both models require that 12 MB be reserved for system use. Both models contain 2 SD card slots. Both can be used for storage cards and the right slot is also an SDIO slot which can be used for interface cards such as camera and networking. Bluetooth 1.1 is standard and used for networking and wireless gaming. A Bluetooth button/light is located on the top edge of the Zodiac. Only a few games currently support multi-player, but the Bluetooth can be used to connect to a network, mobile phone, or internet access point. An interesting use for Bluetooth is InkStorm, a built-in application, which allows multiple Zodiacs to share a chat / whiteboard form of communication.

Besides the standard Palm OS 5.2 applications, the Zodiac includes:
Tapwave MP3 Player
Tapwave Photo Viewing Application
Kinoma Player for viewing videos
WordSmith word processor
PowerOne graphing calculator
InkStorm chat and whiteboard application
Web internet browser
