Well, I hadn't heard that, but that doesn't mean you're not right.
To be honest, I prefer B&N's DRM. If B&N went out of business tomorrow, my copies of B&N ebooks will be readable as long as I have a copy of the software and remember my own name and credit card number.
On the other hand, if Adobe decides to change it's DRM scheme (which it's done at least once in the past), I'm screwed as soon as I upgrade my computer.
(This all assumes I don't liberate my ebooks, of course).
I'm sorry about the stupid geographic restrictions...I'll admit, as a US citizen, I haven't been very sympathetic about that in the past. But some recent experiences trying to find books I could be with a gift certificate I was given to an Irish ebook site has brought home to me how frustrating it could be!
