And it's nice to be able to type on it again - seems better than the previous one too, and pretty close to Apple standards in terms of responsiveness.
Getting dell out for the work (next business day onsite) was a pain in the parts, having to go through online stuff first, then not being offered a number to call or a form that could be completed. Google sorted that, but I was quite cross by that point, but the chap in India with the temporary fake US accent was patient and polite. It was still better that Apple's return to base warranty, where you take stuff to the store an hour away, they demo that it doesn't work while telling you there's probably not a problem and then send stuff away on the proviso that you'll pay if they can't find a fault. If I ever bought another Mac at full price it would NOT be through Apple again.
Apparently this battery is starting to swell too. :-p
