Apple PowerBook Duo 230 with Dock
Apple released the PowerBook Duo 230 in October 1992 at a hefty $2,610 ($6,050 today), and what a powerhouse it was. This small laptop, weighing only 4.2 pounds and measuring 1.4 inches by 10.9 by 8.5 inches, fits neatly into a briefcase or bag, eliminating the bulk that made other portables of the time difficult to transport. The reason for its slim appearance is that the internal floppy drive had just been removed totally, and engineers went to town on reducing weight wherever possible, a move that reflected what they had done previously with the PowerBook 100, but on a whole new level.

It’s part of a long-standing military challenge: fixed-wing aircraft provide maximum speed, but only if you have a runway to land on; helicopters, on the other hand, can take off and land almost anywhere, but they can’t fly as fast. The X-76 seeks to address this.

This is Not a Space Jellyfish, Just a SpaceX Rocket Launch

SpaceX Space Jellyfish Launch Florida
On February 4, 2026, a bright glow appeared in the sky over Florida that morning, and people were literally “stopped in their tracks” as they gazed upwards in an attempt to catch a glimpse of the gigantic and almost unearthly apparition hovering in the sky. These long tendrils were connected to a massive dome-shaped head, and they were all surrounded by a delicate cloud of pastel pink, blue, and gold colors.

Compaq Presario 4402 All-in-One Computer 1996
In 1996, families looking for a home computer had the same old problem: a cluttered desk with different boxes, cables strung out everywhere, and setting it all up felt like launching a small rocket.
