Hey, j_kubart, although it's not the first time I'm answering this same question, I feel like typing today. Here's the advantages of the Nook’s (both e-Ink black & white and Nook Color) over Kindle:
- Any Barnes & Noble store provides free Wi-Fi to Nook's
- Nook allows to lend books for 2 weeks to friends or to your other devices that run B&N app (PC, MAC, Android phones, Apple iPhone and iPad, etc.) Barnes & Noble allows (when you walk in with the Nook to B&N store) to read any available eBook for free while in the store via free provided in the store Wi-Fi. With Nook, while in BN store you get exclusive articles from top authors, and great offers including cafe treats and unique deals.
- Nook (unlike Kindle) can be used for library ebooks.
- Nook (unlike Kindle) can be used for renting text-ebooks.
All of the above is true for both Nook e-Ink and Nook Color eReader/tablet.
Nook Color is worth mentioning separately as this is a hybrid Android eReader/tablet device, something between Kindle and iPad. Even though Nook Color has LCD touchscreen, it's a new generation screen which is anti-glare coated and is better performing in sunlight and produces less glare all of which are dooming reading on iPad. Also, the screen is amazing and readable/viewable at wide angles.
Overall, Nook Color is more than e-Reader as you can also watch video and use Android applications on it. It's a hybrid device, much more than just an e-Reader but not a full tablet as it doesn't have a camera. If all you want is to read novels, Kindle (or the original e-Ink Nook) might be better for you. If you want something more from your device at half of the price of iPad or Galaxy tab, then Nook Color is your best bet.
Nook Color has several apps that already come with the device (Pandora Internet radio, QuickOffice, etc.) Also, Barnes & Noble recently released Nook SDK and Nook Developer platform that will allow most of the existing 100,000 Android apps be ported to it. Also, you can use the Social Settings screen to link your NOOK Color to your Facebook account and your Twitter account. You can also import all your contacts from your Google Gmail account. Once you have linked to Facebook and Twitter and set up email contacts, you can lend and borrow books, recommend books, and share favorite quotes with your friends.
