Trying to keep up with this fast moving PC and mobile technology. Not always on top of most recent, but trying.
I've been at this as a Physicist, Mathematician, and Electrical Engineer since before Gates wrote his first operating system pre Microsoft and Jobs built his first Apple (I forget what that was called). Built and used one of the first Commodore 64s and many others since. And was in Naval electronics installation and repair (including cruise classified systems) before PCs. I am not a computer science geek or programmer - just via osmosis, learning about various technologies, my personal experiences consulting on PCs, along with logical deduction and reasoning.
