It was surprising to figure that internet access is not limited. I wonder where I've heard that only wiki was accessible, probably it was my imagination. I guess browser with limited functionality solves the "users intensively web surfing at amazon's costs" problem.
Regarding Kindle vs Sony Readers, well, I think the fact that most guys that I know, who have small e-reader business use Sony-s speaks volumes. On the other hand, it doesn't mean that Kindle is bad, it's not. It actually is the best choice in under 150$ price range for many users, depends on what people need of course, I actually often recommend it to guys on some Georgian forum.
What I don't like about kindle is rather amazon's policy:
1) amazon store lock / no epub support /can't get ebooks from libraries (doesn't matter in Georgia
) Amazon being able to remotely delete books on kindles.
2) Amazon is way too powerful a book store, controlling e-readers would give them even more power, which cannot be good for customers.
