I thought this article was worth reading for this tidbit: "If you’re not sure if you’re a candidate to buy a Mac, here’s a simple test: If the notion of a really well-designed AC adapter excites you, you’ll probably be very happy with a Mac. And if it doesn’t, you won’t."
The post doesn't really make it clear, but most if not all of these figures look to me like Jobs has been getting design patents (not utility).
