I'm waiting for my realforce to come and wondering if I will be able to use HHKB keys on it. I'm going to use it with OS X and windows bubble key will really irritate me so I thought about swapping windows and alt keys with Meta and Alt keys from HHBK. Will they match? I'm talking about the black on black set. Colour looks similar but I'm not sure about the texture and height of the keycap.
