PDAs are appropriate for taking brief notes and for maintaining schedules, contact lists, and task lists. Also, PDA users can read, edit and create email messages on the PDA for future synchronization with the workstation's email software. Small, limited applications exist for inclusion on a pda . If a user desires the same performance and output as a workstation, then the user should choose a laptop computer. A laptop computer is a workstation.
Laptop computers are either thin laptops or full laptops.
Thin laptops are thin. With most thin laptops, the case contains the motherboard and the processor. The hard drive, the CD-ROM drive, and the floppy drive may not be in the case. The drives are external peripherals that plug into the computer. Most thin-laptop computers do not offer the same experience and functionality as a desktop workstation.
