Pocket sized...

Micro-miniturization has been happening for years. I had Micro machines. Man, could that guy talk fast.

But in a world where, 16 years ago Hughes Research lab produced a focused ion beam approximately one three-millionth of an inch thick (it hurts to think), it's safe to say we're obscesed with small. Every food worth eating is available in "bite size". Heck, google pocket superheroes (polly pockets for the boys).

So tell me...

What is your most/least favorite "micro" thing?
What thing should/should not be miniturized?
