The chairs also have an MP3 cable jack, and are "compatible with all tablet PCs," including the iPad. You won't be able to get one right away, though. The chairs are due out this fall.

There are 30 distinct positions, including a locked lean-back mode. The arms swivel out so you can show a tablet to the person next to you. The chair has 45 patents based on posture research.

The Asus Chromebook Flip, shown here in tablet mode, offers two USB 3.0 ports, a mini-HDMI port, and an SD card slot, plus an audio jack. Dressed to impress.
