If the iTab (that's what they should have called it) had the ability shut that off and still read, we'd know about it. That's not the sort of lede you bury. It'd be one of the more revolutionary features on the device.
With Pixel Qi screen tech, you can shut down the backlight and still have text be perfectly readable in direct sunlight (I'm not yet clear on just how much indoor lighting you'd need to read it with no backlight at all). The power savings are fantastic. As to its effect on eye strain, that's unclear, though not having white light pouring off the screen is bound to help.

Not only the Pixel Qi screens have the property. As I can read my PDA perfectly in bright sunlight with the backlight turned off. Every single transflective screen has this property. Only Pixel Qi has taken the concept of transflective screens and has made some updates on it.
I'd have been surprised if the HP Slate had had a Pixel Qi screen. Considering those aren't in production yet. We'll have to wait till they go in production and then see what tablet builders will use it...
