I dunno, I think some aspects of this layout make a lot of sense. If you're entering a lot of numbers on the number pad with your right hand, it'd be nice to have arrows for your left hand to control where the numbers are going...this layout gives you that, while the TK layout doesn't. I can also relate to the goal of wanting the arrow keys closer to the letters, and with replacing the right modifiers with something more useful (I could easily live without them entirely). Might be even better with the arrow keys on the other side of right shift, and 1.25 left and right arrows. No windows key on the left isn't what I would have chosen, but I'd consider this a preference choice; I feel like there are definitely people out there for whom the windows key is something that they only ever press by accident. Big enter is fun, but small backspace is not; it's too bad that the two features traditionally go together, although some companies have managed to combine a big enter with normal backspace (though, in this case, some solution would be found for where to place \|, since the area around right shift is already full). The main thing would probably be adjusting to the moved ?.
