I can only use it as a laptop 1% of the time and it still makes perfect sense because otherwise I would have to own a separate device for this 1% of the time.
That makes sense. Though I think it depends on what you're doing for that 1%. For me personally I prefer a beefy desktop for work+games, and a low-power laptop/tablet for portable jobs.
That way I can upgrade the PC tower every couple years and keep using the same portable device for years and years, since it's basically just an email/web/SSH terminal. I've been using the same desktop PC since 2009, just upgrading it as needed. Over 15 years it feels like fewer devices than having to keep replacing a high end laptop every 3-4 years or so.
