Who would have guessed

I've been stumbling a lot recently (ever since I installed Firefox on the Mac). Hence the sudden surge in crappy posts recently; and here's another one :p

Pictured below is an IBM mainframe hard drive, dated from the late 80s/early 90s. It is a HUGE 1 Gigabyte in size. Of course, back then, 1g WAS huge. Very huge actually. My XT computer around 93/4 had a huge 10 MEGABYTE hard drive in it. About 1/76 of the memory my VGA has on it nowadays.
This drive was used in the mainframes of the time, and you literally had to be an engineer to install and run the damn thing.
Obviously, the SD card pictured next to it is exactly the same size, 1 gigabyte. A lot smaller, faster, and way lighter than it's great great great grand daddy.

So who would have thought it back then, if someone had told you that one day you could hold a little card that stores 1 gigabyte, would you have believed them? Would you have believed that a small card as big as a stamp can carry 748,899 High Density Floppy Discs?
Of course, if some one had told you that a card EVEN smaller than that (Micro SD) can carry the same, then you would have classed them insane and called the mental police.

And in another 10 years time, when we'll have whole computers as big as a stamp we'll be wondering if we would have believed it today. I certainly do....
