Thanks very much for you guys' thoughtful answers.
Another curiosity just came up to me.
The Pocketbook IQ is said that it is open to any 3rd party applications.
I understood this as the meaning that I can install any android apps into my IQ.
Now, I'm wondering where I can find or puchase the 3rd party apps for IQ. Does it mean that I have an access to the Android Market? or shoud I find a way to the android app markets by myself just as the pandigital novel had been hacked to have an access to the Android Market?
