Also one of the more popular brands of Windows CE handheld devices put out by Casio. There are numerous models (including HPC, Palm-sized PC, and Pocket PC versions). They are still not as popular as the iPaq, in their most modern incarnation.

The Palm-sized PC, and Pocket PC varieties are MIPS R4000 chips (others are ARM and SH3), and they can generally take one or two expansion cards. Lovingly known as "Cassie"s, they fill in a good percentage of the older CE 2.0 devices (slightly more pervasive than the trouble-riddled Jornadas).
