I purchased a mechanical keyboard for home and work and I've been having fun with them. I prefer the feel of the mechanical switches over the typical rubber dome contacts that are included in most cheapo keyboards that most people use. Recently I also purchased a "grab bag" of keycaps that fit on the switches that my keyboards use so I could customize the look of my keyboards. Here are some pictures of them.
Here's my keyboard at home. I didn't swap out all the keys because they are backlit and I wanted to be able to see them in the dark.
