The Cherry MX Blue was first made in 2007 and has become the most popular model for people who, like myself, have to type for a living. The word ‘blue’ refers to the type of switch, and is the loudest one. Some switches on these mechanical keyboards are silent but the noise is all part of the pleasure of using it, for me at least. I love the sound the keyboard makes but I love even more the fact that using it has eased my RSI considerably.
