And get dirty so easy! How often do you guys clean yours and what do you use? I just use micro fibre towel with a bit of water and rub. And I use canned air on the keys, Im shocked to see how dust gets in between the keys so easy. Its definitely a lot more maintenance than a regular laptop keyboard because of the fabric. This is why Im always cleaning the screen of the SP3, because when you put the cover on top, the dust just falls into the keys.
