Comment 3G module = $50 extra (Score 1) 191
There's probably going to be an option to get an unlocked 3G module with SIM card reader, but it'll currently cost you at least $50 extra. But it'd be unlocked and you could use any SIM card you want from a telecom that allows any device on their network and provides SIM cards for that.
In Europe you can get SIM cards for free and only have to pay starting 5€ per month for data services on it, especially for the few hundreds of megabytes per months which are probably enough for downloading e-books and doing basic web browsing.
