Personally, I loved the first gen iPod with the jog wheel, and the clear exterior of the cube, and the powerbook 12". You'll notice they all come from about the same timeframe, I truly think that was the golden era of Apple design.
That was design without regard to cost. By the time they transitioned to Intel, they were still about design, but it was a much more cost-efficient and machined design.
A case could be made for almost all of them, but I had to go with iPod classic.
I didn't notice I could vote for more than one. Back to the polls!
For the individual that is surprised about the iPhone 4, it is by far my favorite phone design, and mine looks as beautiful as it did on launch day... Not even a scratch.
No original iphone?
