But neither the Unboxing Remote or Sal's Remote actually stuck, so what's the deal? Our commenters have noted over the past few days that aluminum eats magnetic fields, so it could be that the aluminum makes sticking the Remote on a no go. I don't know exactly how it worked with the old iMac (whether there was just a magnet inside or in both the Remote and the iMac), but Sal points out his Remote won't stick to the fridge either. After he told Apple that, they even offered to send him a new Remote, so maybe the Remote he has is defective (which means this is the second new defective product we've heard about in the past few days). One more wrinkle-- other commenters have suggested that instead of the side, the Remote now sticks to the "chin" of the iMac, but Sal tried that and said it didn't work either.
At any rate, Apple says the Remote should stick, but everything we've seen says it doesn't. Which is it? Anyone have a new iMac and want to confirm that it sticks? It's not a big loss, of course, if it's really not sticking. But like the Open Apple button, that's another special Apple touch that's been lost on the new iMac.
Update: This video, courtesy Rizza in the comments, shows the Remote stuck on the front right corner of the glass (which is one way to get around the aluminum, I guess). So looks like Apple moved the magnet there.
