July 13, 1994: PowerBook 150 Introduced
One of the first low cost PowerBooks introduced was the PowerBook 150. The price was nice but Apple made it clear that this wasn't the top of the line model, or even close.
The PowerBook 150 lacked, for the time, the ever useful ADB port and sported a muddy looking passive matrix screen. On the bright side, the screen did feature a desktop equivalent 640X480 resolution. The 5.8 pound machine also featured 33MHz 68030 chip and a whopping 3 hours of battery life.
The PowerBook 150 was introduced in July of 1994.

Comments
I had a PowerBook 160; talk about your muddy screens! Anyone remember the term “submarining”?
But I have to say, I did prefer trackballs to trackpads, even if you had to periodically remove and clean the former.
