Losing your luggage is no fun, but while companies like Trakdot have been selling trackers for some time, a startup is taking to Indiegogo to create what it calls the "world's first smart, connected carry-on." Bluesmart is a small suitcase with a host of features that its makers believe frequent travelers can't live without. Priced at $235 (or as low as $195 for early adopters), it'll include proximity tracking to alert you if you walk away from your luggage, a TSA-approved lock that's controlled by your smartphone and a built-in battery to charge your gadgets. There's also a scale integrated into the handle that'll tell you how much your bag weighs just by lifting it off the ground, and a quick-access compartment for storing your laptop.
