j720.jpg (64352 bytes)The Jornada 720 is one of the latest Windows CE handheld PCs from Hewlett Packard. The result of 10 years of evolution that began with the HP-95LX, the Jornada 720 is a superbly capable machine. Equipped with a keyboard that's usable to a ten-fingered typist that I am, a built-in modem, 32 MB of memory, a bright, high quality color display, and the application suite that comes with Windows CE 3.0, it is surprisingly useful. Shortly after I acquired one, I began using it daily, for replying to e-mails, writing notes, and the like.

Alas, the Jornada 720, just like other Windows CE machines, is not programmable. No native development tools exist for this machine. That is not to say that you can't write code for it (as a matter of fact, I wrote several applications for it myself, including a telnet utility), but the development tools are cross-platform; they run on a regular Windows PC, only the object code is downloaded to the handheld.
