A wireless ebook reader isn't particularly useful without a decent ebook store. As long as we have restrictions on parallel importations of books it is unlikely that Amazon or Sony etc will sell to Australians. I doubt there is a big enough demand for ebooks for Australian publishers to create their own ebook store. So if the government follows the Productivity Commission's recommendations and removes the protectionism on Australian publishing we might have a wireless ebook reader by 2012 but probably not earlier. Alas,
the way things are going, I'm not optimistic...
I'm hoping people figure out how to hack the Sony Reader Daily Edition to use non-US SIM cards.
