The majority of users only consider the utility and convenience provided by such devices when making purchases.

The most glaring differences between PDA (Personal Digital Assistant, a handheld computer that is) and PC relate to the size and weight (a PDA has an average size 120mmx80mmx17mm, and weighs around 180 grams).

The hardware of PDAs has some differences compared to that of the PC. First of all handhelds do not have Hard Disk (except some Palm), but store persistent information on the ROM, or on memory cards (usually SD OCF). Handhelds, with the exception of the newer ones, do not have USB ports, so to connect peripheral devices (such as a keyboard or a GPS module) is used CF slot, or the Bluetooth connection.
