Many calculators of this type are monochrome LCD, some are four-color (red or orange, green, blue, and black), or, in the case of some machines at the top of the line as of January 2022 color similar to monitors displaying 16 or 32-bit graphics.

Some have a touch screen, buzzers or other sound producers, internal clocks, modems or other connectivity devices including IrDA transceivers, several types of ports for peripherals like printers, and ports for memory cards of a number of types.

The wide availability and low cost of [[personal computer]]s including [[laptop computer]]s, [[smartphone]]s and [[tablet computer|tablets]] gradually made programmable calculators obsolete for most applications. However, they remain popular in [[secondary education]],. where specific Specific calculator models are often required for use in many mathematics courses. Their continued use in this applicationeducation is usually justified by the strictly controllable functionality available. - forFor instance, the calculators do not typically have direct Internet access and so cannot be used for illegal assistance in exams. The remaining programmable calculator manufacturers devote considerable effortslobbyheavily to encouragingencourage the continued use of these calculators in high school mathematics. <ref>{{cite news |last1=Kosoff |first1=Maya |title=Big Calculator: How Texas Instruments Monopolized Math Class |url=https://gen.medium.com/big-calculator-how-texas-instruments-monopolized-math-class-67ee165045dc |access-date=30 March 2022 |work=GEN |publisher=Medium |date=25 November 2019}}</ref>
