If you're using a PC you can likely just get 2 keyboards. It'll use a little more desktop space but you can put them wherever you want. I've found that the mac doesn't respect "left keyboard shift right keyboard letter a for a capital A" which is annoying.

That's... creative, I'll give you that. That wouldn't leave room to put my trackball anywhere convenient. In fact, nothing about that sounds convenient, but if it works for you, more power to ya.

For most people, "wherever you want" is going to be with the outside edges a bit wider than your shoulders and vaguely parallel to a little diagonal. That's not possible with really any pair of full keyboards I've ever had.

I just moved them around until it was comfortable; it ended up with them being a bit further apart than shoulder width, the keyboards certainly weren't close to bumping into each other even though they were standard garbage 101 key USB business keyboards; I think they end up about a foot apart at the closest. Give it a try.

Space them vertically. The left one to the top, giving you a space on the right for the mouse. Or the right one to the to top, then your mouse would be under it.
