Is the whole non-replaceable battery thing such a big deal? I've never taken the battery out of any of my laptops, and the Air has a huge 5hr runtime to make the need to swap between two batteries much less of a necessity. Anyway, the replacement battery is pretty cheap, and free install on that too.

Whats with the 300 GBP difference between UK and US pricing anyway? I thought the difference on the other Macbooks was less.
