this is very interesting - why is the UK keyboard 'slightly' different - surely that would cost Apple money to do this?
I recently purchased a MB iSkin and it's exactly the same as the keyboard - interesting to learn that the MBP has been changed for different markets - however I would have though the US would have kept the physical dimensions for all english-type keyboards.
Over here in the UK, we have a slightly different layout for the keys on all our keyboards, just like most countries are different.
Just a quick snapshot, but as you can hopefully see, while the layout doesn't match up exactly, it still fits on properly, and there's no problem typing on it:
For some reason the @ and " are swapped around - on the majority of keyboards here " is above 2. The Apple position for these is considered to be the "American" one. (although it makes more sense in my opinion)
I don't think the Macbook covers are up on the UK store yet - I ordered this from iSkin directly, but the "Pro Touch" one worked fine on my Powerbook, and I don't see why it wouldn't on the MacBook Pro.
On the UK store, there are three different layouts you can choose when ordering:
Keyboard (local) & Mac OS (français)
Keyboard & Mac OS
Keyboard & Mac OS (français)
