XK04 Foldable Keyboard

I would say ProtArc has a Goldilocks problem. I have ProtoArc 3 keyboards because each one seemed close to what I needed but each has a problem. And returned a 4th. I want them to get this right! XKO4: This is my 4th try with ProtoArc. I love the way XK04 folds in half + No case, but very good leatherlike backing. But it's too small. And my thumb rests on the the obtrusive metal hinge and hand positions are unnatural. What if you could expand the the keyboard by pulling out a bit? Here's the Goldilocks problem: My first ProtoArc is the : K-90A. Exact Right size. Came with silicone keyboard cover. nice. It's my desktop keyboard. Works like a dream. Problem: Not very portable. I guess I could, but it would be subject to banging and bopping in my backback. Was foldable the answer? First foldable: XKMO3 - totally a bust. the keyboard is split in the center and the ergonomics are totally wrong. I returned this. Not a good product. Second foldable: XK01: Although I didn't want a numeric keypad on the left, it folded and provided a normal typing experience on the QWERTY keyboard. Plus, handsome leather carrying case. Almost perfect....but Problem: The PrintScreen screen is right next to the QWERTY part and I keep hitting it. At the end of the day I have 30 or 40 images on my desktop that I need to delete. Can I disable this button? Remove the number keypad entirely? And one problem that all keyboards shared. Too flat. I bought little hinges to stick to the back of my K-90A. $5 but works like a dream. Why not add adjustable lifts to your keyboards. Fold flat when you travel, props up to your desired length when working. Also: The products are alll a little different. One has a silicone layover. One has a leather case. One has a mouse with it. Anyway: Contact me if you want to discuss. I'm not an ergonomics expert, but I am a consumer that wants to love your product.

Works well. One minor complaint- it's a little slower to use the delete key because I have to press the Function key.
