This has been out for a while, but my IFTF colleague Brad just told me about it last week. It's the $400 Juicero juicing machine. To make juice with it, you must subscribe to receive pre-masticated produce that comes in packs (priced between $7 and $10 per pack, $35 to $50 per week). The packs are marked with a QR code that the Juicero scans to make sure it is "fresh." If the pack gets "out of code" (i.e., it's produce you grew, traded, or brought elsewhere) the Juicero will reject it. It's got a built-in Wi-Fi radio, which checks the date (and monitors your use of the juicer). The machine itself seems pretty neat – it presses the juice by squeezing the fruit, but they really need to let you use your own produce.

If this appeals to you, here's a smart floss dispenser you'll probably like.

UPDATE: A spokesperson for Juicero sent me an email, asking me to make some corrections to the piece:
