I personally hate Apple keyboard. If I ever got an Apple Desktop it would be the first thing along with the mouse tossed into the spare parts bin.
A keyboard that isn't too soft, though not too hard, nice tall keys.
Again more info would be required.
You have ergonomic keyboards, Standard keyboards, other designs that fall between them.

Depending on your price point it depends on what you get.
I like the HP 2004 Standard keyboard.
