I remember in the Navy, we had a saying- "The only difference between a fairy tale and a sea story is that a fairy tale begins with, "Once upon a time..." and a sea story begins with, "Say, this is no sh*t!" Perhaps we are spinning yarns, and dreaming wildly but you can never tell! Things change, and at an astounding rate, and even if you are in the industry, and can see the 'seamy' side of the digital world, you have to admit that in the next few years, somebody, somewhere, in some lab is gonna shout, "EUREKA", start planning his golden parachute, then announce a multi-mully-gigglebit chip, probably with an entirely previously unknown substrate that allows an effective 'film' speed of no less than 6400, and be user controlable to record scenes in the range of 200 to maybe 1100 nm, and after another two years, they come in disposable cameras- once the lithium batteries die, you just buy the next generation!! He may even call his ole buddy Jim Brick, the Software Maven up and get him to do the microprogramming!! I have seen a lot of amazing things in the last few years, so I am not going to be shocked if it happens, and even not disappointed if it doesn't, but it is fun to speculate!! Say, Jim, what do YOU want for Christmas!!?? :o) Dan ( Here comes Santy-Klaus,,,,!) Post I DON'T suffer from insanity...
