Thats what I thought, thats about half the annual operating cost of my personal vehicle. And it does provide me with a lot of value. Its for brainstorming, maintaining contacts, keeping track of projects, etc.
Just a side observation: Many people on HN do make money building software, yet so many users seem completely unwilling to pay for software. In some regards I do understand that, there are quite a lot of "bad companies" out there that you just can't avoid in many circumstances, but as far as I'm concerned, Obsidian seems like the good guy (for now at least).
Personally? Iam at odds with the subscription model for apps but may be better than paying for every major release.
I recently started to think about buying software instead of doing a half good job programming something
If it was just $2250 for 45 years, maybe. That's not a payment option. The price will probably go up with inflation. It's probably closer to $4000-8000 after inflation, as $50 will become $100 after a decade or two.
If you go to the extent of including inflation, you should also account for the fact that your income will also likely increase - with raises accounting for inflation and career progression - making the price of a tool that can provide so much value even more negligible.
