That is a very nice layout. I like a lot of aspects of it. Having x<>y and R-down on the side there, as they are used regularly, having up and down near the actual menu makes sense, as you're likely to be using the menu soon after. I also agree that y^x, 1/x etc are more used than ln/log, and more so than trig. Yes, helpful to have exit somewhere in a corner - I think most people think of going to the corner to get out something, so it seems natural.

It also makes me think that it would be nice to have an HP-like calculator that could use a separate alternative stack for programs and the solver. I like the unlimited stack, and my programs so far have returned the stack to how it was beforehand, but it would be nice if calculations (like the calculations that go on for sin/cos/tan etc..) happen off your stack, returning your answer to ST-X.

Actually, thinking about it more - couldn't you just take x, y, z and t off into a few registers, and then return afterwards? That way you won't lose your stack?
