Santa didn&rsquot manage to slip this smart case in our stockings in time for us to ring in 2016 with instant photo prints, but us selfie addicts are not giving up and we are getting it on our list early for the holidays, and are turning our US cousins up sweet. The Prynt basically transforms your Samsung Galaxy series or iPhone into its own Polaroid-style printer-fitted camera, with very little extra dimension added. No cartridges needed, only Zink paper (or stickers), times 10. The app links each photo to a video too. $149, pre-order on www.pryntcases.com or await restocking on www.amazon.com.
