The traditional stapler is one where you have to push hard to make a decent staple. The new stapler, such as the Staples stapler, requires only a click, and it does the job for you - flawlessly.
Most middle and high school students still use the old clumsy scientific and graphing calculators (or even worse - basic calculators) from over a decade ago, such as the outdated TI-30X (1993) and TI-84 (2004). Now, there are infinitely better (and even cheaper) choices, like the Casio FX-115ES Plus, TI-36X Pro (2011) and TI nSpire graphing calculator with large color display.
Incandescent lightbulbs have been used for over two decades. They are highly inefficientl and are being replaced (slowly) by other lights, such as fluorescent lamps. An incandescent lightbulb glows because it produces heat, which is a problem because the heat wastes a lot of electricity. A fluorescent bulb produces less heat, so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs. That's why you can buy a 15-watt fluorescent bulb that produces the same amount of light as a 60-watt incandescent bulb.
