Sparkfun USB Host shield

I am thinking of getting the USB Host shield to read in from a USB keyboard. has anybody worked with this shield? is it as easy to interface with as a PS/2 keyboard, or am I just better off to use a PS/2 keyboard?

The research I have done suggests it may be a lot more code to use the USB Host.

my intent is to use a micro wireless keyboard for my alarm project for configuration.

Mainly just curious is all.
