News Summary

• Dyson built a billion-dollar business by taking sleepy home appliances and trying to make them less annoying.
• When those products hit, they hit big; when they don't, they're big flops.
• The company is launching the CameraJet, a $500 toothbrush with a tiny camera that scans a user's molars and sprays mouthwash between them.
• It promises to remove the annoyance of flossing with synthetic plastics — but also asks users to be comfortable with a camera peering at their teeth.
