Comments: Happy New Year

Okay, I'll byte. ("Oh gawd, not that joke...")

5 meg. I've got a nine-year-old PDA with a 4 GIG SD memory card. That's on the order of a thousand times the capacity of that behemoth. The difference? The 1956 IBM storage device could be taken on a plane (obviously, from the picture) without earning you a body-cavity search from the TSA.

("You just had to go there, Arnold, dincha?")

I remember my first computer, with its ginormous 40-Meg hard drive, and I wondered how I'd ever fill it. Now that 40-Meg is a third of the Windows operating system's footprint.

Think of this: the capacity of an audio CD is about 700 Meg. It would take over a hundred of those IBM storage units to hold the first disk of the "Berkeley Square's Greatest Hits" compilation. That's a sobering thought.

Here's another: the capacity of a DVD is about 4.5 Gig - a thousand times the capacity of that unit. If you stop at the video rental store on the way home from work, spend five minutes picking out a movie, and ten minutes driving the rest of the way home, your effective "download speed" is 300 Meg/minute (4.5 Gig/15 minutes) or 5 Meg/second. Until the advent of fast Internet connections, your computer couldn't compete with the video store.

And the times, they are a-changin'.
