I have one of those. While they're very much a descendant of the Model M, I'd say their quality control is lacking. The PageDown key on my keyboard is much lighter than all the other keys, it feels really mushy and doesn't have the same tactile feedback that it's supposed to have. All the other keys are fine. I can live with it, but I never saw such an issue with any of the Model M keyboard I've used.

Also, their USB firmware sucks. Sometimes it won't work during bootup (say, if I want to go into the BIOS or pick something from the GRUB menu), and only gets properly initialised when I get into linux or windows. This only happens sometimes. Other keyboards work consistently, and the problem disappears if I plug the unicomp into a KVM switch that actually shows up as its own HID device instead of just switching the USB ports around. I've seen other keyboards with similar problems but for such an expensive keyboard, it's really quite annoying.

I've had the failed to initialize problem with many keyboards, including my Kinesis. If you're using a UEFI bios it could possibly be related to fastboot being on.

I have one, and I found that problems with it not working during bootup were related to its large power draw. It's been working fine for me since I plugged it into a powered usb hub. YMMV.

Thanks, that makes sense. I remember the original model m's were real power hogs, to the point that USB->PS/2 converters rarely worked with them.

Now I wonder if they're just using the original circuit with a tacked on converter... might have to open it up to check.
