How complicated can a keyboard get these days? I plugged it in and it worked. It was a comfortable size.
One word of warning: This is an ISO layout, rather than an ANSI layout. ANSI is more common in the US, while ISO is common in Europe/Japan. (You can see the wikipedia page on "keyboard layout" for more information).
The thing to be aware of is the position of the enter/return key. On most US keyboards, it's horizontal, next to the quote key. On this keyboard, it's vertical, with an extra key squeezed in. You can easily get used to this layout, unless you change keyboards often. In that case I would recommend making sure all your keyboard match, particularly in the position of the enter key.
