What kind of stuff is he doing that anything less than top of the line isn’t acceptable, and he replaces it every 1-2 years? That’s a wild upgrade cycle, and since he’s describing a pretty awesome machine, seemingly quite wasteful. My previous daily-driver laptop got replaced 7 years in (and even then it’s still functioning, the years of “abuse” made it hard to use as a laptop, so now it sits around as one of many servers).
