Calibre does not strip DRM from ebooks, so it cannot transfer most Kindle books to a Nook. You have to first strip the DRM from the file. There are a few utilities to do this, but they tend to be cumbersome.
Calibre is the easiest to use program I've ever used. I tend to rely on my brother or my dad for some of the technical stuff I need done once in a while and this was something I was very easily able to use myself for converting AND transferring files onto my kindle without help. Big plus. I'd give it a try if I were you.
Not straight away. The books from amazon generally have a DRM encription on them and are not in a straight pdf or epub format. The nook only reads pdf or epub. You would need to find a program that would strip off the DRM (note this is illegal) and then convert it to a pdf or epub format.
A lot of people were together after Christmas last night and were discussing this issue. Amazon is missing a HUGE market, as every single Nook owner there said that they would probably purchase a lot of Kindle Books if they could read them on their Nooks. Yet none of them thought they would also purchase a Kindle in addition to their Nook.... so as I see it, by Amazon restricting their access, they are wiping out a HUGE potential market of ebook readers. I thought they were more market-wise than that!
well with any business they want to sell there product. with their restrictions on ebooks it will force ppl to buy the kindle over the nook and same goes for nooks restrictions aswell. if they would had made it possible to get nook books for kindle or kindle books for there nook then those companies will lose profit because ppl dont have the buy the kindle or nook in order to read one another files. remember the nook and kindle are in competition with one another and the only thing that speaks to them are number.
The reason that I got a Nook that you can download books from the library, no charge, and read them on a Nook. Can't do that on a Kindle w/o something like calibre. If I want to own a book, I buy a paper copy. But if I'm only going to read it once, the library is the way to go.
