People justify it by the fact that you use your phone all day, ever day but I would say I use my PC way more than my phone.
In any case, it’s apples to oranges. I can use any old junker for a desktop but a high end phone still means very practical things like longer battery life, longer support assurances, and maybe a handful of exclusives (Dex, full galaxy watch support, uwb tags, etc). The average person is far more likely to notice the difference between a cheap and expensive phone compared to a cheap and expensive computer. Samsung charges what it does because they can because they’re aware that Apple is the only company that offers the whole “package” the way they do and they’re just as expensive.
More and more people switch to midrange and budget phones every year all the same.
The Note 10 was released in August 2019. By Apple standards getting a major OS upgrade at this point is nothing exceptional however in the Android world it's a stand out - and is also proof of Samsung's claim.
(Lenovo let me limit the max charge % many a year ago on my X1 Carbon, I've been wondering why phone manufacturers have lagged behind on this. Here is locked to 85% vs Lenovo's more flexible configuration).
Just gravity-checked my Note10+ getting out of a van on pavement.
No worries.
Needless to say: I won't buy.
I had a Samsung Galaxy S5 a very long time ago and the expandability was very impressive. You could plug in headphones, a microSD card and get new batteries for it. The only real thing I didn't like about it was Samsung's TouchWiz skin, however I am sure that could have been fixed with an alternative ROM, especially given the popularity of the device.
It's a real shame that companies are tying perfectly working phones to old degrading technology.
