I received my Realforce 86u yesterday, and had a couple hours to poke around on it. The overall built quality appears to be superb. I have heard others say the Realforce feels better to type on than the HHKB Pro because of the metal versus plastic backplate on the HHKB. I think I might prefer the HHKB. The Realforce seems to feel a bit mushier to me. Each keystroke on the HHKB seems to be a little more defined, with more noticeable feedback while pressing the keys. I am not sure if it is because I bottom out my keys and the feeling of bottoming out on the HHKB is different from the Realforce? It is hard to put my finger on it exactly, but it just doesn't feel quite as snappy when I am rifling off 100 wpm. Once, I get some time I am going to perform Ripsters "all 45g" mod as the 35g keys feel too soft for my taste. Not sure if I am the only one who has felt this way, but it is just my initial impressions after a short time with the Realforce.
