While the iWatch might be the latest thing lighting up the rumor mill, the concept of the iWatch has actually been around for ages, as this slideshow from the TechHive shows.
The first smartwatch dates way to back to 1941. The Mimo Loga allowed you to make basic calculations using the hour and minute hands, and while primitive, it was very effective. They are extremely rare to find today.
Another huge advance were IBM’s attempts in 2000 and 2001, the first smartwatches to run Linux. They came with a huge 8MB of RAM and storage.
Finally we have today’s versions, the latest example being the e-ink Kickstarter sensation Pebble Watch. You can check out the full range of smartwatches that hit the market on the slideshow.
