A couple of trivial addenda:
16 MB Flash ROM (where the base OS is stored)
64 MB RAM (by default split into 32 RAM, 32 RAM-disk for storage)
"Buzzer" (Not exactly sure on this point, but I believe it can only play a few sounds, not a full speaker)
The flashROM can be read-write depending on your ROM (Oz for example). The same is in fact true for all of the Zaurii.
The 64Mb or RAM can all be utilised as program-running RAM memory by using a different ROM (OZ for example), so you can have all 64Mb to play with.
The buzzer can also be made to play songs, etc. It's certainly a bit tinny, but it can do a bit more than just buzz.
