Retro Mini is a very cool looking handheld device that has the ability to play NES cartridges. Granted sticking the cartridge in the power slots doesn’t make the Mini look more aesthetic, in fact it makes the device look more awkward. The Retro Mini has a 2.4″ LCD screen and runs on four AA batteries. The AA batteries can keep the handheld console running for about 8 hours before a recharge. The Retro Mini costs $49.99.
