Casio
Go through the shops in London and you might find a Casio PDA. Known as the Casio Cassiopeia, some sporting the model number E-125, this PDA was oftentimes referred to as a color pocket PC and Casio banked on the fact that users would enjoy the sleek design and the colorful viewing screen. This Casio PDA contained 32 MB of RAM which could be expanded with detachable and re-attachable memory cards. The color screen itself offered a 240 x 320 display, and for those hardcore Microsoft junkies, Casio was certain to include Microsoft Pocket Excel, Word, Internet Explorer and also its version of Money software. So as to update the data on your Casio - and keep PDA and notebook computer synchronized – you would be able to use a simple USB cable to hook the two of them together.

While it appeared that Casio had found a winner in the Cassiopeia, the prohibitive price put it out of reach of many individuals who would purchase a Casio PDA. Dated reviews on the Internet time and again bemoan the fact that while the idea of this device is great, the huge price tag discouraged too many from actually purchasing this device new, and the few who sold it used on the Internet were not able to recuperate much of their losses. Some users because disenchanted with the equipment because the battery was drained quickly and needed to be either charged or replaced, and when the screen was set to display data in maximum brightness, the battery would drain even faster

While attempting to surpass the popularity of the Palm IIIxe PDA, Casio miscalculated and was not able to garner the same accolades as the competition. Come to think of it, the general public was actually quite unhappy with what it felt was a Casio gadget that lacked user-friendliness. In the wake of these negative reviews, not even the positive highlights that the company sought to feature time and again were able to turn the tide. And those few who did have the necessary funds to add this gadget to their pockets oftentimes chose not to do so. Eventually, the company discontinued the Cassiopeia E-125 color pocket PC. Today you will be able to purchase used models on the Internet and also download free Casio PDA software from a host of shareware sites. Support for the model is virtually non-existent but with the help of message boards you should be able to get most problems resolved.
