First impressions:
It looks and feels like a quality keyboard (it had better, for $100). Not quite as far into the "blunt instrument" category as a Model M, but still solid.
I thought I would need to restart my desktop since I'm switching from a PS/2 keyboard to USB, but the OS (Ubuntu Linux) recognized the new keyboard immediately when I hot-plugged it.
The blue LEDs (Num/Caps/Scroll Lock) are a little on the bright side, but are positioned and angled such that they don't shine directly at your face unless you lean pretty far over the num pad, so I don't consider it to be a problem. I think I still would've preferred some other color of LEDs (e.g amber) though.
It is definitely quite clicky, but IMO slightly quieter than the Unicomp. The pitch of the clicks is higher though -- more of a loud "tick" than the metallic "clack" of the Unicomp -- so I suppose some people might actually find it equally (or more) objectionable. My officemate already commented on it -- he initially thought it was louder than the Unicomp, but upon further reflection (after I pressed a few keys on the old keyboard for comparison) he concluded that it isn't louder, just "different". He didn't think it would bother him, but he was OK with me using the Unicomp so obviously he's not very sensitive to keyboard noise.
The tactile feel is very good; however, it has a noticeably lighter touch that the Unicomp, which will take a little getting used to. I think once I've acclimated to it for a day or two (so that I stop bottoming out the keys so hard) I will likely prefer the lighter touch.
I also tested the key rollover. Every combination of up to 6 simultaneous keys I tried registered perfectly; the 7th press did not (as expected with a USB keyboard). I have not yet tested it with a PS/2 adapter to see if the n-key rollover works as advertised, but I have no reason to doubt it since 6-key rollover appears to work perfectly.
So far, it gets a thumbs up.
