Edit0: I've often found much better (repairable, long lasting) products for myself by looking in the enterprise/ fleet catalog. My oft-mentioned HP Elite X360 is another example of a device targeted to the corporate market and as a result, enables easy replacement of the SSD and battery.
I also didn't claim to know what is good for consumers. It should be obvious that given the choice between thick and heavy or thin and light consumer sales have favored thin and light for the past decade. That's not me dictating what is good, it's just me paying attention to the smartphone market for more than ten minutes.
I am happy for you that you find phones and laptops that last you a long time. Bully for you. But you are not the bulk of the smartphone or laptop market. You represent a tiny portion of both markets. I know this because you have to hunt down phones and laptops with replaceable batteries while pretty much everything on sale at BestBuy is all glued together. Buy the shit that you want but don't pretend that you represent some silent majority quietly yearning to replace batteries in their phones and swap hard drives in their laptops.
Non-replaceable batteries are a net benefit for consumers most of the time. They get the lighter thinner phones with all the features they want. If you want to keep the same phone for a decade, even with a replaceable battery, I wish you the best of luck. In the US I don't think there's any active 2G service and 3G services will be turned off in the near future. It'll make a decent media player or WiFi browser but it won't act as a phone.
