Claboor - I was quite worried about the same kinds of things when I first looked at eReader as a place to buy ebooks. Currently, it's my favorite place to buy a book because I like the flexibility it offers compared to other DRM, and I like the reader software. I still rarely buy a DRM'd book unless it's something like a novel that I'll plan to read and throw away, just like I do with the paperbacks. Except with paperbacks I often give them away.
Here's some info that may help you decide what you think about it for your own case...
Yes, they probably do keep your CC# on their servers, but I think you can delete the credit card info after you finish the downloading. It may remain on backup tapes, but that's no worse than any online purchase.
You could also give them a temporary card number like some companies let you do for a one time use number intended for things like internet purchases. Then the seller doesn't know your real number, but still gets paid, and it still gives them the comfort level of being tied officially to you, so you would not likely distribute it in mass. You can even set expiration dates and dollar limits on those card nbrs. Multiple CC companies offer that. Maybe MBNA and Bank of America and Captial One in the US?
But the CC# never gets stored on the device. You have to enter it (once), but it gets converted by a hash algorithm and only the hash key is stored. That's what is used to unlock the book. Don't remember if it has to decrypt also. The hash doesn't contain enough info to reconstruct the original CC# so there's a level of safety.
To give an idea of how this sort of thing could work, think of entering a 10 digit number into an algorithm that tells you the remainder mod 13. That result between 0 and 12 could be a (trivial example of a) key to unlock the book, but you never have any chance of recovering/stealing a 10 digit number from that remainder key.

Like all DRM, there are things to make you uncomfortable...
* Dependence on the proprietary eReader software to be able to read the books
* Dependence on the eReader web site to be able to "recover" your CC# to unlock, if you forget what you used and, say, buy another pda.
* And, even though eReader is fairly successful, there's no guarantee that they will keep the eReader software updated and top notch, or that if they go out of business altogether there will not be any ongoing way to read the ebooks you bought. (Which is why I generally only buy DRM'd ebooks that I plan to read and throw away.)
But there are some really great features that make eReader's DRM my favorite...
* You can "realign" your entire library of purchased books from the web site to use the same current CC# you give them as your primary. So you only need to remember one name/CC# combo to unlock your books. One exception... I have some books from when they were Peanut Press. Those books don't show up on the web site. Maybe because I used another login, or maybe because they didn't carry over the info to eReader. I don't know which, but as a result I have to keep track of those old books and the name/CC# combo to be able to unlock them. Not bad, but a bit annoying.
* It accomplishes the DRM goal of prevention of mass copying and pirating because people don't want to give away their cc# in mass. And even if someone finds the hash key value, it still requires the name on the credit card used to purchase the book in the first place, which people wouldn't want to give out.
* You can still "loan" a book to a friend with eReader software by loaning them a pda, or by entering your CC# for them. (Or giving them the number to enter themselves if you really trust them, like a spouse for example.) That is a whole lot more like how a real book works. Some flexibility, but the publisher doesn't lose control of the content. Unless the whole thing gets hacked, of course. I don't believe anyone has done that.
Some quick observations about a few other DRMs. Just my impressions... others can clarify and add info.
* Fictionwise, as a seller, has taken a very interesting approach and many of their books are in multiformat, which I think includes iSilo versions along with some other types of formats that you get access to when you buy a book. Not all books are offered that way, probably because the publisher would not allow that. They also frequently offer their 100% refund deal on some very nice books. I think that means you pay for the book, and then get a store credit equal to the full amount you paid which can be used to buy another book at their store.
* MS Reader. Only available for Windows platforms, I think, such as Pocket PC and Windows desktop. I really like the reader, but a lot of people don't like it. I very much dislike the DRM because you tie it to a hotmail or MS passport account. And you only get 3 activations. If you lose those (e.g. when you rebuild your device or PC from scratch) you have to contact MS for more, and I've heard some stories that indicate it's not something you want to try, and might not even be successful. Then the books are worthless if you don't have any activated devices to read it, so the only option you have is to convert them to html with something like ConvertLit, and use something that can read html or convert that again to something your device can read. Same is necessary if you don't want to use any flavor of Windows to read your book.
BTW, there is a way to preserve your activations on PPC..
here's a nice tip from Pocket PC Magazine. But note that while they say you lose activation every time you hard reset, I think you're okay if you restore from a full backup.

Tip #219: Saving Microsoft Reader Activation
If you want to read those e-books on your Pocket PC which have Digital Rights Management protection on them, you have to activate the MS Reader application from the Microsoft Reader Web site. Every time you do a hard reset on your Pocket PC, the activation is lost and you have to go through the whole process of activation again. There is a way to save your activation and carry it back to your Pocket PC after the hard reset. To save your activation do the following steps:
- Click on the Activesync icon which is on the right hand side of the Taskbar on your desktop to pop up the Activesync window.
- Click on the "Explore" option in Activesync to navigate the folders in your mobile device.
- Go to My Pocket PC/Windows and copy the following files:
- secrepid.dat
- secrep.dat
- secrep.dll
- secrep.xml
- Microsoft Activation.unload
- Create a folder with-in the My Documents folder on your desktop PC. You can give a meaningful name to this folder such as "Microsoft Reader Activation".
- Paste all the above-mentioned files into this folder.
- Now whenever you do a hard reset on your Pocket PC, you can copy and paste these files back into the Windows folder of your Pocket PC and your Microsoft Reader application will be activated automatically.
(To copy the above mentioned files successfully, you will need to make sure that the extensions of the files and hidden files appear in the listing along with the file names. In the ActiveSync Explorer window, go to Tools and click on "Folder Options...". Now click on the "View" tab. Make sure that the option which says, "Hide extensions for known file types" is unchecked. Also select the "Show hidden files and folders" option if it is not already selected.)

Sorry, here I go getting lengthy again. Can't help myself! To wrap up, there are a other types also of course. I think iSilo has a form of DRM. You're tied to that reader then just like the others. MobiPocket has a reader that many people really like, and weren't they just acquired by Amazon? At any rate, while people seem to like the reader, they tend to feel the DRM is very restrictive. Adobe Acrobat has a DRM now and I think it's a common choice for libraries who lend ebooks. Personally I don't like Adobe Acrobat because I don't think it works well on mobile devices.
There's so much more that could be said about DRM and even eReader DRM, but I hope it helps with the sort of questions related to eReader and these giveaway books. My advice is to stick with one of the most common formats and don't assume the book will be forever yours to read.
