When I was in high school, you could tell the nerds (we were called 'square' back then) by the pocket protector stuffed with colored pencils and the big K&E slide rule on their hip. My, how times change.
When I started working in 1960, the only calculator was a Friden. It was a monster that went kurchung, kurchung when doing multiply or divide.
The first computer I worked on was an RCA Model 301 that took up two six-foot tall racks and had 4K of magnetic core memory. I later worked on the super computer at that time, the CDC 6600. My Android smart phone has more power and memory than that "super computer" had in 1968.
My first "portable" computer at work was a Compaq portable. It weighed enough to be a boat anchor. It had 168K of memory (note: that is Kb, not Mb) and two 5.25 inch floppy drives. No hard drive, although we put a voice recognition card and a 10Mb hard drive in an expansion box on the back of it. I programmed the voice card using the C language and it took over 3 hours to compile the small program.
Fast forward to today and the wife and I have a couple of desktop computers, two Acer laptops and I have a small netbook for traveling. What a difference a few years (decades?) make. I love my Acer laptop. It normally sits on the workbench in the garage so I can smoke and surf at the same time.
Once in a great while I do use the laptop on my laptop. But, have you noticed that while the laptop computers get more powerful and a little smaller, that your laptop to sit them on seems to be shrinking at a faster pace as the waist line expands?
