Congratulations Eben, Liz, David, Peter and all the others ... what you have created may be the biggest thing in the computer industry since the Univac I, circa 1951, the first commercial computer in the US.
I joined Univac in 1957. I would have been in 1953, but the Korean War intervened.
Later I moved to Young & Rubicam Advertising, where eventually I ran a 200 terminal timesharing computer with a staff of 100 ... Our programming language was Algol and our computer was hooked to the ArpaNet in the 1970's (the precursor to the Internet) with world wide access.
In the 80's I had my own computer business and put 13 products on the market, but wasn't very good at marketing and lost 750K dollars.
In the 90's I did pro-bono systems for Museums, Art Centers, Free Clinics, Meals on Wheels, and community organizations.
I went to work for Phelps Memorial Hospital Center, Sleepy Hollow, New York, USA in 2004 as a programmer analyst and have been developing client/server systems ever since, using Delphi and NexusDB as my database technology.
I plan to work for another 19 years ... after all, I'm only 81....
I love Pi ...It is making me excitedly learn about Linux. It allows me to watch my son;s Rock Band Videos on a large screen ... It will teach my grandson how computers work, and perhaps, my second PI, waiting for a cable, will teach my colleagues at the hospital something about what is under the hood.
I am one happy, old dude, full of raspberry pi ....
have a nice day...
