Practical Example of Technology Advances of the Last Ten Years

Ten years ago, I walked into high school with a brand new Toshiba Satellite 2210 CDT. It wasn’t state-of-the-art, but it was pretty decent for its time. It had a 500 MHz Intel Celeron processor, 64 MB of RAM, and a 6 GB hard drive (which took up about 62.9 cm3, or 0.1 GB/cm3). The laptop had a 12.1″ 800×600 display and outside measured dimensions of 31.5 cm x 26.2 cm x 4.8 cm for a volume of 3960 cm3. It cost around $2000 at retail.

Today, I walk around with my Motorola Droid. It has a 550 MHz ARM Cortex A8 processor, 256 MB of RAM, and a 16 GB solid state memory chip (only 0.165 cm3, or 96.97 GB/cm3; which is almost 1000 times more dense than the hard drive in my laptop!) The display is 3.7″ 854 x 480 resolution. The phone measures 6.00cm x 11.58cm x 1.370 cm for a volume of 95.2 cm3, and cost around $600 at retail1. And it fits in my pocket, and can make phone calls to anyone in the world, and can check email, and can watch videos, and determine my location anywhere in the world down to 4m or so, and I can speak to it and it will do things!

That’s amazing.


  1. assuming you just brought the phone outright with no contract requirements
