  • 1992: PacrPad a precursor for tablet computers
    • Pen input
    • wireless connection
    • “Scrap computer” pick one, make notes & leave. Not intended to be carried around
    • User computing session stored in the network
  • Tablet PCs
    • Laptops with ParcPad capabilities i.e. touch screens & wireless connections
    • Some OSs lack features for effective use on tablet PC
