for: travels with you
stuff that goes in the bag: weight, battery, and whether an airline will even let it on board. the sheets below compare all of it side by side.
Bluetooth Trackers
Item finders compared on what actually decides whether your stuff comes back: which crowd-finding network the tag phones into, whether it has real UWB precision finding, rated range, how long the battery lasts and whether you can replace it, and how much water it survives.
E-Ink Tablets
E-ink tablets, from dedicated writing slates to note-capable color readers, compared on what actually decides how they write and read: how big the screen is, how sharp the e-paper is, whether it shows color, whether it has a front light for the dark, the software platform (open Android versus a locked reading OS), and whether a stylus comes in the box.
