Who said that graphing calculators were dead in the smartphone era? Certainly not Texas Instruments -- if anything, it's showing that there's still plenty of life left in dedicated math machines. Its new TI-84 Plus CE is 30 percent thinner and 30 percent lighter than the regular Plus, making for a surprisingly sleek-looking way to crunch numbers. It has six times the memory, too, so you can store more color graphs and images (and, let's be honest, a fresh copy of Drugwars for goofing off mid-class). TI hasn't divulged pricing for the Plus CE, although its new design and advanced feature set hint that it'll be relatively costly when it arrives in the spring. Look at it this way, though: you might just be the envy of your fellow students when you take this svelte plotter out of your backpack.
