saw thru the whole thread.. what does 75% 60% kb means? and what is PBT?
Normal keyboard you see out there are fullsize keyboard, with around 104keys normally.
When we cut off the numpad corner, the keyboard now remain around 87 keys, thus we call it 87 and some other context call it tenkeyless.
60% is what remain after you cut off the F-keys, numpad, cursors and home cluster. It is also normally referred as mini.
75% is a more rare layout and hadn't be standardized to a definite layout yet, so no much explanation on it. But it's normal size is like that of KBT Race.
For PBT, you need to know the material that normal keycaps made of.
Most normal keycaps are made of ABS and some backlit keycaps made of PC. They are all different types of plastic. PBT and POM on the other hands are also plastic but more of a premium choices over normal ABS.
