Antennas
"...requires non-metallic areas to let its radio signals in and out. This time they take the form of narrow plastic stripes..."
I believe that the antennas *are* the actual external metal stripes around the edges, and the plastic stripes are simply where the antenna ends (plastic = insulators). I don't believe that the explanation that the radio signals are somehow emitted inside and then sneak out through the wee feisty plastic gaps is even the slightest bit valid. At least, not for the primary antennas (might be for GPS and/or bluetooth).
One design consideration is to keep the high-Z open circuit end of the antenna monopoles, opposite end from the feed point, away from the meat machine's nasty low-Z fingers. The iPhone 4 famous 'You're holding it wrong' problem.
