- Oral-B says how long it takes to charge, not how long a charge lasts
- Its travel case doesn't charge; that takes the iO9, $110 more
- The iO8 adds a color screen, a sixth mode and a third head for $30 more
Philips Sonicare DiamondClean 9000: what it gives up
- 14-day battery, shorter than the cheaper Series 7100's 21

- One head in the box, where the cheaper 6500 and 7100 ship two
- The case doesn't charge, though the $160 Series 7100's does
