The Game Boy is an 8-bit fourth generation handheld game console developed and manufactured by Nintendo. It was first released in Japan on April 21, 1989, in North America later the same year, and in Europe in late 1990. It was designed by the same team that developed the Game & Watch series of handheld electronic games and several Nintendo Entertainment System (NES) games: Satoru Okada, Gunpei Yokoi, and Nintendo Research & Development 1.
The Sony Tablet S was released in 2011 around the same time the Xperia Play 2 was cancelled, much like the Xperia Play 2 the Sony Tablet S was also PlayStation Certified meaning you could download PlayStation Portable games.
Sadly an update to the PlayStation Store made the tablet unable to download & purchase PS One Classics.
The Xperia Play is a smartphone with elements of a handheld game console produced by Sony Ericsson. With the marketshare for dedicated handheld game consoles diminishing into the 2010s due to the rapid expansion of smartphones with cheap downloadable games, Sony attempted to tackle the issue with two separate devices; a dedicated video game console with elements of a smartphone, called the PlayStation Vita, and a smartphone with elements of a handheld console, the Xperia Play. Originally rumored to be a "PlayStation Phone", the device shed the "PlayStation" branding in favor of the Xperia brand, running on the Android operating system.
The Microvision (aka Milton Bradley Microvision or MB Microvision) is the first handheld game console that used interchangeable cartridges and in that sense is reprogrammable.
It was released by the Milton Bradley Company in November 1979 for a retail price of $49.99.
The Microvision was designed by Jay Smith, the engineer who would later design the Vectrex gaming console. The Microvision's combination of portability and a cartridge-based system led to moderate success, with Smith Engineering grossing $15 million in the first year of the system's release. However, very few cartridges, a small screen, and a lack of support from established home video game companies led to its demise in 1981. According to Satoru Okada, the former head of Nintendo's R&D1 Department, the Microvision gave birth to Game Boy, the follow up to Game & Watch, after Nintendo designed around Microvision's limitations.
The Cybiko is a Russian handheld computer introduced in the United States by David Yang's company Cybiko Inc. as a retail test market in New York on April 2000, and rolled out nationwide in May 2000. It is designed for teens, featuring its own two-way radio text messaging system. It has over 430 "official" freeware games and applications.
It features a rubber QWERTY keyboard. An MP3 player add-on with a SmartMedia card slot was made for the unit as well. The company stopped manufacturing the units after two product versions and a few years on the market. Cybikos can communicate with each other up to a maximum range of 100 meters (330 ft). Several Cybikos can chat with each other in a wireless chatroom. By the end of 2000, the Cybiko Classic had sold over 500,000 units.
