It's a difficult dilemma - treat it as the valuable piece of electronic wonder that you paid top-dollar for, or use it fully for the job you bought it for (and that paid for it, and for the next one).
I'm always disappointed when I see the first marks around the power port, or a nick appears in an iPhone case etc, but they're made to be used & to be portable. It's equally certain that one day it'll be be an out-of-date paperweight, so make the most of it whilst it's still current.
As an aside, I'm also on a forum for RV / camper-vans - mostly older owners - and many of them seem to be 'preserving' their van as close to new as possible, effectively just 'keeping it nice' for the second owner ... Madness, by all means look after it well, but use the damn thing!
