Sometimes I will use something and realize I’ve owned it forever. It’s a nice change in our throwaway reality. I think my personal record is a bicycle multi-tool I got for one of my first bikes, ~25 years ago. Still have it, still use it. When it comes to electronic devices I have a Panasonic mini Hi-Fi from ~2005. Never felt like changing it.
What’s your record?
How are you dealing with everything being in HTML and full of attachments now?
An email of all html is an unwanted email 99% of the time. Occasionally, I save it, and open in lynx. (When a web site emails a security code.)
Attachments are more of a hassle, because I frequently need those. Save to a temp file, "munpack file", examine extracted files.
