Texas Instruments TI-84
Texas Instruments hopes to leap on the back-to-school audience with the announcement of several new calculators useful up to college level. Topping the releases is the TI-84 Plus Silver Edition; the updated version avoids the typically safe looks of most calculators with the online option of 14 different colors for the front or back, from silver to purple. The hardware itself stores 94 apps (with more transferred via USB) that handle math from pre-algebra to biology and calculus and includes 1,000 SAT/ACT test questions for students exiting high school. TI sells it online today for $135.
Younger or less demanding students can also find similar color choices for the TI-30X IIS and IIB, either of which sports a two-line display capable of displaying algebra and trigonometry, as well as the basic TI-503 SV. All three of the lower-tier calculators primarily sell in retail and go without official prices on TI's website, but should be available as of today.
