Bad news if you wanted the colour buttons, I'm afraid. Here's a link (see below) about some answers from Logitech's Remote Control Business Unit product manager Alex Zaliauskas. It includes this:

"Zaliauskas confirmed the Harmony One is a global model, there will not be a European model (previously designated by a model number ending in 5). So if you were relying on those programmable buttons, too bad - they're gone. You'll have to use on screen buttons instead, which obviously won't always be on the screen when you need them."
