Just back from the Apple Store and just thought I'd point this out to everyone. . .I'm actually pretty disgusted to be fair. Had loads of Apple products, myself. . .so when I was using my iPad 2 last night and rather than use my smart cover I attempted to use the actual button - it didn't work. Brought it down to the store (it's a Refurb as the original one I had , had the glue loose and the bezel was coming away from the aluminium) and he told me that it was out of warranty and that the Sleep/Wake button couldn't be repaired (I'm sure it cost about £5 to fix!) and that i'd need to buy a whole new iPad for £199. Awful stuff. I asked him about a gesture I could use to turn my iPad off - and he said no, that's frustrating, but when it runs out of battery it would go off. Eugh.
