I agree with you, it is a pain to know that whatever you have in the line of technological gear will be short lived. However, I also understand that this isn't all bad. With the rate of change in technology today, making something last for years is a waste of time, energy and money. Most things we buy today are practically obsolete by the time we get it out of the box. That is due to the rapid advances that are the norm for that area.
For those of us that are able to not be obsessed with having the latest and the greatest, we can make do with older technology as long as it serves our purpose. Heck, I still have all my financial records on a 1995 Quicken program. For my uses it is all I need. The bells and whistles of the new stuff are not something that I care to use, so the old does just fine. But, I'm an old coot and really don't want all that stuff, so as long as I can keep that program running with no problems there is no need to upgrade.
I have a daughter that is enamored by all the new stuff and all the gadgets. She isn't one of those, always looking at her phone types, but, she has a million apps. on her smartphone and uses most of them.
So to make a long story longer, I have no issues with planned obsolescence of new technology because it is the era that we live in. This too will one day slow up and some other thing/obsession will take it's place. You know, like the Stone Age, the Dark Ages, The Steel Age, etc.... We are currently in the age of technology and it is, to me, an amazing thing to watch constantly changing, improving and expanding. It's really an exciting time to be in.
