Is that for real?

It's a photo of my desk.

Looks like a torture device.

In the beginning, definitely. It takes a few weeks to get up to full speed on this thing. Feels like learning to type all over again.
After that it's quite handy for the more weird key combinations you previously had to look for. All right at your fingertips.

It could be the best keyboard in the world but I don't think you could get many people to try it.

Not at the price it sells for anyway, no. (1295 USD) I guess it's aimed at the desperate, who are willing to try anything.
