The first computer I bought was an 80286. It came with one megabyte of RAM and a 40 Megabyte hard drive.
I remember reading in a magazine that Western Digital had started to produce a 1 Gigabyte hard drive. At the time it cost about $2000.
Now, I can store 4 Gigabytes on something that'll fit on my keychain, and costs $10.
And, when I was a kid and heard that by the end of my lifetime every house would have a computer, I couldn't help wondering what the heck people would use them for. The idea of using them for communications never even crossed my mind. I wondered why the average homeowner would need a computer? To do his income tax returns? The idea that they'd end up being another form of communications technology never even crossed my mind.
