According to CNET, the device will be about $375 USD. That's actually pretty reasonable for a first generation device.

I would love to see a regular PDA with an E Ink display choice, inplace of LCD. E-Ink says that a color version is coming soon, but what I really like is how nice the display is on the eyes, and the ability to easily read in bright sunlight (right now I always have to crank up the brightness on the LCD, and I still find myself squinting a bit). It probably wouldn't make sense for gamers, but for static information lookup and eBook reading, I think the visual and battery characteristics of this display is ideal.
But then again, I'm the type of guy who still has an old paperwhite VGA monitor in my basement.
