Picked up a copy, this morning, from my local HMV. They only had two in stock and one of them, had a great big dent in it. When the sales person started to take the security tag off the good steel I thought that too was about to have a dent. I kid you not, it took over two minutes for the guy to get the tag off, with plenty of grunting and what sounded like the steelbook getting a bit of a bashing.
Surprisingly the steelbook looked fine after the tag finally came off. Checked it out once I got home and it has very minor alignment issues. When I say minor, I mean I had to use a magnifying glass to see it, so I'm not really bothered by it.
The steelbook does seem to be disappearing off the shelves pretty quickly so if you want one, now's the time to go hunting for one.
