Funny when something is built to do a specific task it tends to do it quite well. Remember (if you're an old fart like me) the timex commercials with the watch strapped to the prop of a high speed outboard motor submerged in a tank of water and revved at high RPM? Those Timex DID TAKE A LICKIN AND KEEP ON TICKIN! Inexpensive,quality made long lasting product for the masses, unlike our now moderately high, and high priced devices designed and built for planned obsolescence. Same thing that happened to cars, built beyond the ability of shadetree mechanics abilities and access to replacement parts.
Well, when all you want is a 200 year old technology, another few years won’t bring much change. When you want to use technology that is still being developed and invented things are going to change a little more often. It’s not so much planned obsolescence as it is just using things before the development is mature. In 200 years maybe computer technology will be so mature that new things aren’t happening very often. Not everybody wishes to wait that long. Some of it is useful enough already. Next year it’ll be better. But that’s next year.
