Tell HN: I used the same computer since 2007 (with minor upgrades)
Give yourself extra life.  Buy the best tools you can.Don't let virtues learned by necessity become the vices that suck up your lifetime.  You'll never get the time back that you spend working on unimportant projects, sustaining old builds, placating unhappy people, working on slow computers, etc.  Unless it's the fastest way for you to deliver whatever good you have to the world, put it aside, especially if you've invested time to get good at tending it.  There's no deeper hole to lose your irreplaceable lifetime.
