You've already seen Nintendo revive the NES and Nokia reintroduce the 3310, so why not resurrect more '90s tech? Bandai certainly doesn't see a problem with it. The company has relaunched the classic Tamagotchi toy in near-original form to mark its 20th anniversary (November 1996 in Japan, May 1997 elsewhere). After years of constant iterations, you're back to simple black-and-white displays and the six initial characters. About the only change is the size -- these eggs are about half as large as the models you might have owned as a kid.
The one catch: as of right now, they're only officially available in Japan for ¥2,000 (about $18) each. Unless you're willing to pay a premium to import them, you're probably better off buying a locally available modern version and reminiscing about your youth. With that said: here's hoping Bandai sees fit to bring its retro Tamagotchi to other countries in the near future.
