Connected luggage sets are easy to find these days, but Bluesmart stands out: as one of the first out of the gate, it has experience its rivals lack.

It's crowdfunding Series 2 luggage that builds on the existing formula with some features that, at first blush, appear to be genuinely practical. Both the 22-inch Cabin carry-on bag and 29-inch Check suitcase include a combination of 3G cellular and GPS that lets you track your luggage anywhere in the world (with cellular reception, at least) for free. If your luggage goes to Bhutan instead of Boston, you'll know it.
