Smaller Than That?

I recently had the chance to play around with the tiny Apple iPod Nano, and my question is, can it (or should it) get any smaller than that? I mean, I remember not too long ago (well maybe a little bit of a while ago) I got the 4th generation iPod that had twenty GB and I though that was a ton. The iPod Mini was the smaller version available at the time and although I prefered its size, it just didn’t have enough space. Now, the Mini has been replaced by the tiny Nano that not only is color, but has an accelerometer, comes in a bunch of wild colors, and best of all comes in 16 GB. How crazy is that?
