I got the Hand Me Down bag just about a year ago. It's been good, it's worn nicely (the interior got grubby quickly but I didn't mind that too much) and it's been on its travels (though I've not updated the blog as often as I should have). I tried finding a cheap, low power way of letting it stream its location but haven't done so yet. Maybe that'll come in the second half of its life.
I won't say I haven't looked at other bags in the meantime, but turning it from product to project means I haven't thought seriously about replacing it. That seems good, a small win.
