• The first portable computer was the IBM 5100
• It weighed 55 pounds (25 kilograms), even with this weight it was
much lighter than any other computer at that time.
• This computer is not like the laptops we imagine/see today when
we here the word “laptop”, but it made a path for the development
of truly portable computers.
1981
• The Osborne I was the first truly portable computer and is
recognised as the first laptop computer.
• It weighed 24½ pounds (11 kilograms) and had a 5’’ (12.70 cm)
display.
• This computer was developed by Adam Osborne, in April 1981
• In that year Epson released the first portable computer with a
built-in printer.

3. 1983
• Radio Shack released the TRS-80 Model 100 portable computer in
the U.S.

• It was invented and firstly developed in Japan, but Radio Shack
bought it from Kyocera

screen, it weighed 20 pounds (9 kg) and was sold for $995.

15 pounds (6.8 kg)

4. 1989

6. • As technology is developing they find new solutions for different
problems with laptops every year.
• Today laptops are extremely popular, maybe more popular then
desk PCs.
• While I was searching for the different informations I was pretty
surprised by the development process of the portable computer, I
hope you all liked and found my presentation as much as I did.
• Have a nice day:)
