I have the MNT keyboard on my desk at home and its quite nice. I dont think it's clicky like a model M but it certainly makes a lot of noise. A fellow hacker who owns a Reform said they were notified of the excessive noise both at home and at a local coffee shop.

My only gripe is the keys feel a little cramped and I had to get used to the weird del key placement and the split space bar. Though I still much prefer the happy hacking 2, the MNT keyboard on a laptop sounds very nice.
