Flickr Find: Grampa Mac Portable, meet the baby MacBook Air

It's hard to look at Patrick McCarron's snapshot of -- how many generations? Hard to count -- many generations of mobile computing development and 22 years of Macintoshes on the move without being a little bit awed. The Mac Portable, 1989's answer to getting things done on the go, seems simultaneously quaint and grotesque next to the sleek and dramatically faster MacBook Air. A trackball! That keyboard, that screen! And the floppy drive -- while the newest member of the family doesn't even sport a built-in optical drive. I don't even want to think about how many iPads would fit inside that case.

You've come a long way, baby. Here's to another 21 years of portable computing, Apple style.
