* The pocketwatch had become a rare sight by the end of World War I as men started wearing wristwatches instead. By TheNewTens, however, it was popular again to check the time by reaching into one's pockets, now that cell phones had surpassed watches in timekeeping devices and, well, people commonly store their cell phones in their pockets.

* Biplanes, while largely obsolete, still see use in certain niches where short-takeoff-and-landing ability are favored over airborne performance, to include things like cropdusters. One military design which was introduced surprisingly late was the [[https://en.wikipedia.org/wiki/Antonov_An-2 Antonov An-2]], a Soviet-designed biplane transport intended for use from short or improvised airfields and popular among such players as North Korea and North Vietnam (being able to takeoff from and land in any flat-ish clearing is handy when any sizable or well-built airfield is likely to be a target of the United States Air Force). The airplane proved so versatile that it saw an upgrade in the form of the turboprop-powered [[https://en.wikipedia.org/wiki/Antonov_An-3 Antonov An-3]], which was introduced in the 1990s.

** Somewhat less dramatic but [[SchizoTech far more entertaining]] was the brief trend of taking piston-engined aircraft (typically transports or tankers) and fitting them with jet engines (in ''addition'' to the piston engines, not ''instead'' of, mind you) to give them additional thrust. While many of these aircraft's top speeds were limited by their airframes, the additional thrust did mean they could carry heavier loads, such as was the case for the [[https://en.wikipedia.org/wiki/Fairchild_C-82_Packet Fairchild C-82 Packet]] and [[https://en.wikipedia.org/wiki/Fairchild_C-119_Flying_Boxcar C-119 Flying Boxcar]]. For the tankers, such as the [[https://en.wikipedia.org/wiki/Boeing_KC-97_Stratofreighter KC-97 Stratofreigher]] (itself a much-redesigned spin-off of the B-29 Superfortress), it allowed the tanker to keep pace with the jet bombers it was meant to refuel (previously, refueling had to be done with the jet bomber idling its engines with flaps and airbrakes extended, following the tanker as it went through a full-throttle ''power dive'' to try and stay ahead of the gliding bomber it was refueling).

The practice mostly went out of fashion with the introduction of both jet-powered transports and the turboprop engine (itself being a relatively small turbine engine turning a large propeller).

* There have been more than a few cases of obsolete aircraft receiving a new lease on life via various design upgrades. One dramatic example is the [[https://en.wikipedia.org/wiki/Basler_BT-67 Basler BT-67]], a rebuilt Douglas DC-3 with such upgrades as a strengthened and lengthened fuselage, new turboprop engines to replace the old piston engines, new avionics, and modifications to the wings. The end result is an aircraft with all of the strengths of the DC-3, but with greater carrying capacity, range, speed, and of course a renewed service life for the 1930s-era DC-3. Given that over 16,000 DC-3s were built (including military variants, licensed copies, and even foreign knock-offs), there are more than enough airframes and parts to keep the popular aircraft in service.
** Another similar example is the North American P-51 Mustang, which saw various rebuilds and upgrades, including the [[https://en.wikipedia.org/wiki/Cavalier_Mustang Cavalier Mustang]], originally designed as a high-speed VIP transport, but which would evolve to become an attack plane for the export market, and the [[https://en.wikipedia.org/wiki/Piper_PA-48_Enforcer Piper PA-48 Enforcer]], which featured a turboprop engine and was marketed as Counter-Insurgency (COIN) attack plane. The Piper Enforcers were so heavily redesigned and rebuilt, that they only shared about 10% of their parts with the original Mustangs which they were originally built as.

** When tanks first appeared in WorldWarOne, they were lightly armored and mainly fired high-explosive munitions for infantry support. By the end of WorldWarTwo, they had become well-armoured machines with guns that could fire high-velocity shots to pierce increasingly heavy armor. However, the development of increasingly effective shaped-charge warheads during the UsefulNotes/ColdWar led to a belief that no amount of protection could be assured against such weapons. German and French tank designers responded by reducing armor to increase mobility and focused mainly on having their tanks' guns fire high explosive anti-tank rounds at long ranges. However, all of these changes were reversed by the development of composite armor and ERA (explosive reactive armor) blocks, as well as smoothbore guns firing kinetic energy penetrators with extremely high velocities, thus returning to the paradigm of a heavily armored tank with a high-velocity gun.

*** Diesel engines also need next to zero modification to be converted into burning biodiesel, a fuel with almost zero carbon footprint. In fact, the first ever Diesel engine are built burning cooking oil, the precursor of modern biodiesel, as its fuel. Biodiesel are also fairly cheap as they can be made from kitchen and slaughterhouse waste, lowering the demand for city landfill capacity. Some cities, like Shanghai, have its entire bus fleet converted into running on biodiesel and new buses are biodiesel/electric hybrids. Also in Shangai citizens with biodiesel, compatible cars can buy biodiesel from bus companies at a price much lower than petroleum diesel, and the conversion fees, if any, are partly covered by the city. Biodiesel generally has the same fuel mileage as petroleum, and the natural lubricating property of biodiesel reduces the wear and tear of the engine.

* Most home video game consoles stopped using cartridges in the mid-nineties in favor of [=CD=]s. The sole holdout Creator/{{Nintendo}} proceed to demonstrate why the others had moved on as cartridges' advantages such as faster load times and no need for separate memory cards were vastly outstripped by how much data CD Roms could hold and at a much cheaper manufacturing price. Since then, games have gotten larger and now take a significant time to read from the disk, while cartridges have become smaller and cheaper with the advent of flash memory. Nintendo, after three generations of disk-based systems is switching back to cartridges for the UsefulNotes/NintendoSwitch.
** It should be noted that Nintendo never stopped using cartridges for their portable consoles.

** Mechanical switch keyboards used to be commonplace in the 80s, then over time, keyboards makers switched to rubber dome switches probably for cost reasons. Now, mechanical keyboards are all the rage again due to their reliability, as well as other features like tactile feedback or easing the ability to "rapid fire." Heck, even the old IBM Model M, released in 1986, is becoming a well sought after item.
