What's 4.3-inches diagonally, costs $200 to build and has absolutely no reception issues when held as shown in the image above? Why, the Open SciCal! Matt Stack, the genius who pieced this gem together, relied on a 1GHz ARM Cortex A8 CPU, 8GB SD card, WiFi module and a spartan web browser in order to concoct what's likely the most desirable graphing calculator this side of Pluto. The handheld device weighs about 1.6 pounds, runs Linux as well as the statistically inclined R, and is reportedly capable of doing roughly twice as much crunching as Texas Instruments' Nspire . Skeptical? Considering that this bad boy sucked down stock data from Yahoo! Finance and ran auto-correlation on the numbers in order to near-instantly report current trends, we're guessing TI (or any other graphing calculator company, really) has no room to argue. Hit the source for more details, and don't worry -- that feeling of insignificance wanes with time.
