But. You're stuck if you want the standard cursor + home block keys layout. And I hope you like having substandard buttons (which wobble, and sometimes need to be pressed twice to register) replacing the function keys. And hopefully you didn't use the programmable or media buttons on the NEK4000 - the included toggle switch is a band-aid on a bad design decision. (Incidentally, I couldn't use the included mouse for any length of time without noticeable discomfort, as the way my little finger splays outwards (even at rest) meant it was continually dragging along the tabletop no matter how I held the mouse - the downside to an ergonomic design is when you don't quite fit within the parameters for which it was designed.)
I've just gone back to my NEK, and while it feels like typing on marshmellows in comparison, the decisions they made in order to reduce the number of keys (and keyboard size) have left the Sculpt keyboard as something of a lame duck for my purposes.
