Why a slide rule and pad of paper is better than a computer 1. A Slide Rule doesn't shut down abruptly when it gets too hot. 2. One hundred people all using Slide Rules and Paper Pads do not start wailing and screaming simultaneously due to a single-point failure (on the other hand, 100 people using slide rules don't get to have office chair races in the parking lot). 3. A Slide Rule doesn't smoke whenever the power supply hiccoughs. 4. A Slide Rule doesn't care if you smoke, or hiccough. 5. You can spill coffee on a Slide Rule; in fact, you can use a Slide Rule while completely submerged in coffee. 6. You never get nasty machine fault messages. 7. A Slide Rule and Paper Pad fit in a briefcase with space left over for lunch. 8. You don't get junk mail from Keuffel & Esser offering pricey software upgrades that fix current floating point errors while introducing new ones. 9. A Slide Rule doesn't need scheduled hardware maintenance. 10. A Paper Pad supports text and graphics images easily, and can be easily upgraded from monochrome to color. 11. Slide Rules are designed to a standardized, open architecture. 12. A Slide Rule is immune to viruses, worms, and other depredations from hostile adolescents with telephones. 13. Additional Paper Pads can be integrated into the system seamlessly and without needing to reconfigure everything. 14. You don't have to make payments to own one. 15. Most importantly, nobody will make you feel bad by introducing a smaller, faster, cheaper slide rule next month. By the way, is there anyone who has actually enjoyed breaking in a new TI-89? Are those the most user hostile device ever invented or do I just know dumb people? (kind of like Microsoft upgrades - when you hear coworkers screaming in agony, you tend to put off upgrading your own computer as long as possible). Edit: You would be shocked to learn what forum I got this list from.
