Garmin Fenix 5s Sapphire: notifications from my phone with custom replies, 6 day battery life, buttons. No touch screen (operate it "blind" and in the wet), waterproof, scratchproof. You do need to pay extra for the sapphire screen. Swiss Army knife (they're sooo well made) Under armour underwear: no seams, last ages, extremely comfortable. Darn tough socks: extremely comfortable, last forever, never smell. Altra Lon…
They made design decisions that prevent simple things like "installing a .deb package from the host filesystem without keeping the package in an image layer", then fixed some of these with that weird buildkit thing that you need to enable in the settings.
It's very useful for sure, but I wouldn't call its CLI interface well-design.
