From page 3 of Engadget’s massive iPhone review, regarding the Calculator:
Missing from the iPhone, though, are dedicated tip and scientific / graphing calculators, or, perhaps more usefully, a tip calculator.
If you know enough math to even know what a scientific calculator is, why would you need a “dedicated tip calculator” mode? Take the total and multiply by 1.2 for a 20 percent tip.
