In previous eras, I would have had to remember my way when I go out running, lest I become lost, harried by wolves and eventually freeze to death, scared and alone whilst trying to construct a crude shelter from twigs and leaves.
But now we've got geosynchronous satellites to do the work our brains used to struggle with. Fuck remembering shit. Just run, and let technology guide you home at the end of the day. Come spring I reckon I'll be taking my new gizmo out into the wilds for some serious derivé. It's even got topographical maps and stuff, so you can survey your local mountain range and program some challenging routes.
A truly awesome toy if you can foot the bill.
