Stop making split keyboards! You don't need 2 separate pieces; all you really need are slightly angled keys away from the center. See the Truly Ergonomic keyboard[1] for example.
That layout also has the advantage of being a design you could use for a laptop, if only manufacturers put actual effort into their laptop keyboards.
There's room in the world for both designs; it's not really a zero sum game (unless you consider that people designing truly split keyboards would otherwise spend their time designing angled keyboards). Split keyboards can help accommodate people with different body types from yourself. I have a Kinesis Advantage 2 and it is ever so slightly too narrow for what i'd prefer for comfort with regards to my shoulders. When a keyboard is truly split you can adjust each side to be placed where it is best for you.

Citation needed. What if I don't like the angle TECK chose? Laptops for sure should start slightly angling, but if the unit is separate from the computer, why rant against user choice?
Keyboards should be truly split for two reasons:
a) different people need the spacing between the sides to be different. Ideally, based on the length of your shoulders.
b) some people, like me, like to put our pointing device (mouse) in-between the two halves
That layout also has the advantage of being a design you could use for a laptop, if only manufacturers put actual effort into their laptop keyboards.
