Barnes & Noble announced Monday that he Nook Color App Store has reached the 1 million download milestone.

While that isn't much compared to the Android Marketplace or Apple's App Store, it's important to remember that the Nook Color accomplished this feat with a limited selection of apps and within just one week after the Barnes & Noble rolled out its over the air software update to its e-readers, allowing users to download additional apps.

The original announcement made it seem as if these apps would all relate to the device's use as an e-reader, but the top selling apps for the store tell a different story. The top five apps for the Nook app store in the first week included Drawing Pad, Solitaire, Astraware Mahjong and of course Angry Birds.

With B&N's announcement of its own app store and the addition of Flash support, the Nook Color is starting to look less like just another e-reader and more like the best entry level tablet on the market.
