Joshua Topolsky in the wrap-up section of his review:

if you’re a hardcore reader with an appetite that extends beyond books to magazines and newspapers, the Color is the first viable option we’ve seen that can support your habit. […] But besides all the reading you’ll be doing with the Color, you’re also buying into a potentially much bigger proposition — namely, the idea that come Q1, this thing will be a viable Android tablet with an app store of its own.

The user-interface is a tad sluggish, but at $249 you’ll have a hard time finding a better device that’s priced this low.
