There are many subtle differences between the Kindle and the Nook and the "better" choice depends on the features that are most important to you. I would suggest checking out the manufacturer's website for each and looking at the product specs.
an ereader is basically Nintendo events
Kindles and Nooks are both ereaders. The Kindle is manufactured by Amazon and the Nook by Barnes and Noble. They support different file types, but at a similar cost, they are more similar than different.
Not with any ereader only ones like kindle fire and nook color you can always check other ones though
The best place to examine e readers side by side would be on amazon. There you can read customer reviews in which people say why they think which is better and so on.
On a eReader(if you have a one): examples: - Literati - Nook - Sony - Pocketbook - Kindle
Both the Nook and the Kindle have very high reviews. Each are supported by great companies and have great book marketplaces. Each company has an entry level ereader and a higher end ereader and both companies have a tablet as well. You can't go wrong with either company.
Using an ereader is convenient, but carrying around a phone, tablet computer and an ereader gets cumbersome. Popular ereaders like Nook and Kindle offer iPhone, Android and iPad apps so you can read books anywhere. The apps are free, and you can buy books just like you would with the Kindle or Nook. The books are sent to your device via 3G or wi-fi.
The top sellers for eReaders are Appleå«s iPad Mini, Kindle Fire HD, Nook HD, Kindle Paperwhite 3G, Nook Simple Touch with Glow Light, Nook Tablet, Nook Color, Kobo Glo Wireless eReader, and ECTACO jetBook Lite.
I hear that the Amazon Kindle is better, based on online reveiws and such.
No the nook color has better ratings but nook tablets are better yet
Kindle for sure it has more to offer than the Nook & the pricing is totally worth it.
Kindle because you can get more books for free.
