It started out pretty simple. And with a real world case, too. I'm debating a new keyboard, as this one starts to act up — I'm sick of wireless, I'm sick of batteries, I'm sick of PS/2-to-USB adapters, and it seems the hardware starts failing me, too. That said, I was very happy with the ergonomic ("split keyboard") Logi — it was good to my wrists, it held up for ten years, and it certainly is one gorgeous keyboard —, and if the SafeType doesn't do the trick for me, I'll be looking to get a variant of the Logi that's not wireless. Anyway, the SafeType is also a split keyboard, but they mean it. It's like hacking a typewriter in two in the middle, and then putting both halves of the keyboard upright so they keyboards aren't horizontal, they're vertical. When you type, your hand are not parallel to your desk, but orthogonal to it. It did wonders for me when I tried the "upright mouse", so I think the keyboard may be beneficial, too. The rub is, you don't have cursor keys that way. So I needed to find a way to put the cursor keys on the main keyboard.
