Whee! I can't wait for it to get here, but it is going to be taking a bit of a long route due to the extra fees that Amaon.ca charges. That said, I have already ordered a case and screen protectors for it and I am looking at a skin to make it look pretty. :)
This one does have ads on it, but I hear they are unobtrusive and easy to ignore. There are also some other freebies that come with it but I cannot recall what all at the moment.
I have a tonne of books already downloaded for it, free from Amazon, and my library has a program where you can borrow books to read on it. :)
One of my favourite features is the backlit screen for reading in bed. It is designed to be a low light unlike my blackberry which is bright.
