Here in Silicon Valley, I was reminiscing this morning about my very first computer, which I bought in December of 1985. It was then called just "the Macintosh" and just after I purchased it, I was able to upgrade the internal memory from 256K to 512K. Wow! There was hard drive, of course. A few years later a I bought a 20-megabyte external hard drive, which could store virtually everything I had in digital format. (In contrast, the iMac now in my study at home can handle 750 gigabytes of storage; that's 37,500 times the capacity!)
