Good grief. iFixit has pulled apart the new iPod Shuffle:
Is this the future? A single IC, a battery, and some user interface components. Amazingly, at least on our scale, both halves weighed 5 grams. That means the entire functional half of the iPod weighs only about 10% more than a single sheet of letter size paper.
Hit the link for some photos. Spoiler: Most of the parts are dime-sized.
