The Wii Mini is widely considered to be one of the worst console redesigns in gaming history. It's not backwards compatible with GameCube games and peripherals; it can't access the Internet, making it impossible to download Virtual Console games or WiiWare titles; it only has AV output... the system's inferior in every way to the original model of the Wii.
Well, almost every way. The Wii Mini features a top-loading disc drive, something no other console has boasted since Nintendo's own GameCube. While it's not as high tech, there are a lot of benefits to this type of drive. Sony's recent redesign of their current gen-console, the PS3 Super Slim, also features a top-loading drive, and it's definitely a change for the better.
As you will see, the method used by the Wii Mini and PS3 Super Slim for loading discs is superior to those used by every other current and next-gen console for a number of reasons.
