My first laptop was a noisy brick with a 486 chip, 8 MB ram, 800x600 px res., 1 hour battery life max., cant remember hard drive size, DOS/win3.1 :).
I am writing this on a silent laptop, 16GB Ram, 2880x1800 px res. with 8 hours of battery life, and SSD storage. OSX 10.9.3.
We as collective did this. We learn the laws of nature. If it does not exist, we invent it. If it does work, we improve it. I am enthusiastic!. Development is accelerating, cars drive themselves now. Using mainly dino-corpse to power our hi-tech gadgets is antagonistic to the direction we are taking. Solar and wind work but they are toys, we need more terawatts, we are working on it. I won`t bet on when or who is going to do this, but it is coming, as I see over-unity devices popping up everywhere. It reminds me of the computer fairs of old.
