Just the heads-up for those who are still scratching their heads why they didn't know about the Kindle DX earlier... Amazon does not offer an upgrade program for the Kindle DX. Alright. But if you bought a Kindle 2 in the last 30 days, you can return it to Amazon for a refund and
order a Kindle DX instead.
Of course if you are happy with the portability and cuteness of your K2, there is no need to follow this advice.
