Uncertainty over the keyboards is precisely why I postponed replacing my laptop.
I'd probably use my iMac more if I could find a keyboard & trackpad combo in the same form factor as my laptop's. I want the trackpad flush and centered below the keyboard. I've used cardboard wedges to fake the arrangement, but it's not the same. And since Teleport has stopped working, I haven't figured out how to use my laptop's inputs across devices. (First world problems, I know.)
