If you're too excited about Apple's own Mac keyboard, then perhaps you should take a look at the Logitech K380, which is a really cheap keyboard that has a few unique features.
I recently reviewed the K380 and liked it a lot. Not only are the keys round (which promotes a fun design from Logitech), the keyboard types very similarly to Apple's older Wireless Keyboard. The key spacing is nearly identical as well.
The K380 can also connect to up to three devices over Bluetooth, so you can connect it to your Mac, iPhone, and iPad and easily switch between the three by pressing the corresponding button on the keyboard.
At only $40, it's a keyboard that looks and feels much more expensive than it really is.
