Kindle Vs. Nook? at least today the Kindle wins, with the initial reviews of the Nook not flattering.
On ZDnet “Pogue just killed B&N’s Nook“:

I have to agree with Pogue’s verdict on the Nook. What we have here is a device that exists as a knee-jerk reaction to Amazon’s Kindle, and the shortfalls show just how badly the project has been rushed to get the device out of the door in time for the holidays.

and NY Times “Not Yet the Season for the Nook“:

That “color touch screen,” for example, is actually just a horizontal strip beneath the regular Kindle-style gray screen. (In effect, it replaces the Kindle’s clicky thumb keyboard.)

This screen is exclusively for navigation and controls. Sometimes it makes sense; when you’re viewing inch-tall book covers, for example, you can tap to open one.

At other times, the color strip feels completely, awkwardly disconnected from what it’s supposed to control on the big screen above.

Worse, the touch screen is balky and nonresponsive, even for the Nook product manager who demonstrated it for me. The only thing slower than the color strip is the main screen above it. Even though it’s exactly the same E Ink technology that the Kindle and Sony Readers use, the Nook’s screen is achingly slower than the Kindle’s. It takes nearly three seconds to turn a page — three times longer than the Kindle — which is really disruptive if you’re in midsentence.

For now stick with the Kindle.
