The LEFT keyboard is specialized for PC games on TV. Unlike other keyboards - keypads - lapboards for PC games on TV that have a full keyboard, this one has removed the keys that are not directly useful for PC games. So it has a much larger mousepad and is more practical for games on the couch. At the same time, it has a mechanical half keyboard with programmable macro keys. While the user can also type full text on the mini keyboard it has.
In the office, it offers a range of ergonomic advantages in work and play. It allows for typing in two different ways (standard and like on a mobile phone) and thus helps protect the hands from the same repetitive strain of typing. While at the same time it becomes the main keyboard for PC games.
