My first brush with PDA info
PDA is Personal Data Assistant. PDAs are handheld computing devices also called Palm Tops; they can also encompass the Pocket PC category of handheld device.
The PDA started off as electronic personal organizers, an electronic replacement to the old analogue (hand-written) style Day Runner or Franklin. The biggest advantage to the electronic day planner was that it could be synchronized with your PC and therefore all your notes would be backed up and replicated, never to be lost as any notepad is extremely susceptible.
some more soon :)
