Okay, so I've got a couple questions. As it hasn't really had any effect on my keyboarding, I haven't spent too much time worrying about keycaps, but I'm curious about where I can get some more information on the different types of plastic, and some benefits of the different types. Also, I'd love to see a pic or two illustrating thin vs med vs thick PBT, just so I have a reference. What are generally considered more preferable, and are there any quantifiable reasons?
