Apple Tablet to compete in new Home Portable market
Apple is developing a consumer-level tablet system...
The unnamed tablet system -- featuring an 8.4" backlit TFT-display and built-in Airport Extreme -- will be marketed as a 'Home Portable' ... battery life is said to be targeted for up to five hours and the unit is operated via touchscreen and displayed keyboard. A docking station, which will include an external keyboard and mouse, will be available for an additional charge.
Current prototypes are wrapped in a dull black casing and feature an Infra-Red port, though such capability is said to be for internal use and will most likely not make it to production. ...
