The lead-acid battery powered 15.8 pound Macintosh Portable

This is what mobile used to look like. Christopher Phin, Macworld:

Yes, the Macintosh Portable is the spiritual ancestor of the MacBook Air in that it took everything that was great about the Mac and made it portable, and it’s even true that the basic recipe of a screen, keyboard, pointing device, battery, CPU, and storage all wrapped up in a clamshell design is common to both—but the difference in weight is staggering. That’s an apt adjective, too, since unless you’re prepared for it, if someone hands you a Macintosh Portable you are apt to stagger a little as your center of gravity shifts unexpectedly.

Quick, funny post. It really drives home how far along our current mobile computing lifestyle has come.
