Random rant: In 1970, Intel produced a memory chip, the first, capable of storing 1 kilobyte of data - a couple of paragraphs of text or so. Today, one can obtain memory chips that store many gigabytes of data - enough to hold entire movies, encyclopedias, and more - for mere hundreds of dollars. So, why is it that when I finish pumping gas at a gas station and hit the "RECEIPT YES" button, the piece of crap machine can't store that one simple keystroke in its input buffer long enough that it doesn't have to ask me 5 seconds later, "RECEIPT? (YES/NO)". It can remember a credit card number, do complex fuel tax calculations, and even tell me about the latest sugar-coated crap I can buy inside, but not that I pressed that button a few seconds ago. It's a scary, scary world we live in, folks. Bah!
