So can a product be
open and saddled with
DRM? I think the answer is... basically. You see, all book readers support DRM (this is not the same as requiring DRM). Without it, publisher's wouldn't allow their books onto it (very few book publishers support unencrypted books).
The segment is much like the iPod was in the early days of the iTunes Music Store. Yes, it supported MP3 and unprotected MP4 files. But to buy music online it came with DRM. In fact, the Kindle and the Nook are very similar, in that they support multiple devices sharing one purchased copy - each account can authorize many devices to share content. Apple pioneered this, and it really made the DRM tolerable. Now all my Macs, PCs, Apple TVs, iPods and iPhones plus my wife's PC, iPod and iPhone all could share the same 99 cent song. In fact, it was arguably more convenient than a CD. Sure I couldn't post it online and let everybody grab it, but that's illegal anyway. But I could copy it onto all those devices, no "ripping", no blank CDs to buy... within the realm of what was allowed, it was very easy to do. If the computers sat on the same network, you could even stream the music without copying or downloading - very handy indeed!
Kindle and Nook have nailed this too. Authorized devices under an account can read the same book, be it a PC or Mac (Amazon's Mac software is not quite released yet, however), an iPhone, or a eBook reader.
So why do I find the Nook superior? Support for non-proprietary formats. Amazon has latched onto the MobiPocket file format, which they added custom DRM to. Want to buy a book? It must be available without DRM ... or purchased from Amazon.
The Nook supports their own format as well, which I understand to be a modified version of ePub that is rumored to become available via SDK from Adobe to other manufacturers. That means, in theory, those books could be loaded onto another eBook reader that supported ePub, such as a Sony. But not a Kindle, since Amazon doesn't support ePub. In addition, the Nook supports the usual open, unencumbered formats, such as PDF, PDB, and non-DRMed ePub. But lastly, it supports Adobe's DRM engine for ePub. There are lots of independent stores using this, and their books can be loaded onto your Nook. In addition, it's becoming increasingly popular at libraries, which means you can go to your local library to get a card (because who has a library card these days), and then go home, go online, and check out an ePub version of a book and load it for a few weeks onto your device. That's right... FREE bestsellers! Finally, Uncle Sam is subsidizing something that ACTUALLY benefits ME!
Since supporting books without DRM is useless, (what books?!) this ePub support is actually very, very important. It allows for price competition (Borders is about to open a store which will be large enough to compete with B&N's prices, unlike some of the third party stores that either have lesser titles from lesser known authors, or high prices). It allows for portability. ePub is popular enough that it will last a few years for sure - so one can bring their ePub books with them to a new reader should you move on from the Nook. If the rumors of B&N book compatibility with other ePub readers becomes true, you can even move their own books to a new reader. In the meantime, Barnes and Noble, being a bookseller not a hardware manufacturer has already licensed their store technology to another eBook reader manufacturer, so there will soon be multiple choices from multiple vendors. Kindle? Amazon books only on an Amazon provided Kindle or Kindle DX.
So what do you do if you have a Kindle but want a Nook? You can carry both until you finish reading all your old books, and then have access only from your PC or iPhone. You can rebuy your books on a Nook, but that doesn't sound like a good idea. Or, you can logon to your Amazon account, download each book, understand that any Topaz books (they will download onto a PC with a .tpz extension) cannot be converted, and for the rest, use the questionably legal utility
described here. The utility is pretty much only for techies. It's a Python script (you'll have to download and install Python on your PC - a Mac already has it). It's command line driven (no fancy GUI). It's ugly. But it works.
Once you've done that, you'll have a bunch of unprotected .mobi files. Take those files and load them into
Calibre which can convert into any number of formats, including non-protected ePub. It's actually a great tool - it can even manage the synchronization process to your eReader, including Kindles, Nooks and Sony's (oh my).
When you are done, you'll have recuperated most (perhaps all) of your Kindle book investment, depending on how many Topaz files you had. You might even get $150 or so on eBay for your old Kindle, meaning you can do the conversion for $100 give or take a few books you have to rebuy.
