I know sensors are getting bigger, but where will this all end? Do we really need all this card space? Would like to hear peoples views....
"I think there is a world market for maybe five computers."
-Thomas Watson, chairman of IBM, 1943
"Computers in the future may weigh no more than 1.5 tons."
-Popular Mechanics' scientific forecasts in 1949
"There is no reason anyone would want a computer in their home."
-Ken Olson, president, chairman and founder
of Digital Equipment Corp., 1977
"640Kb ought to be enough for anybody."
-Bill Gates, 1981
The above quotes (especially that last one since it deals with memory) are what several "experts" said in their time of computing history. No one can predict what computers (and technology) will be in the future. Also, you may be only looking at your view of the world and you can't see the rest of the trees in the forrest.
Most consumers are only familiar with 35mm films, but there are commonly used film formats that are larger than 35mm, called medium format and large format. Medium format is 3-4x larger film surface when compared to 35mm, and large format is even more. With most consumer (and prosumer) cameras we're talking from 3 to 5 to 8mp...with medium format digitals it's more common to talk about 11, 16, and 22mp...the 22mb camera making a 121mb file.
There's a whole other issue of video capture on a memory card...due to the amount of info in video today's card capacities just can't compete with video tape...just one more reason why larger capacity cards are needed.
No one can say what the future will bring.
