I do have a backup laptop, which does come in handy for the rare case of, for example, making a new install.
But yeah, i feel like a laptop is an awkward middle ground between a phone and a desktop. It’s not as powerful and has a small screen, but it’s also not as portable as my phone.
Granted if i travelled more i would need a laptop, and then i would have a dock of some kind at home to extend its capabilities (USB hub, second monitor, etc)
The life expectancy of 75 is an average (of the US population i assume), billionaires are likely to live longer
