It is interesting that at least one very small change has been made to the Sony store page that lists the Reader.
Sony Reader "Purchase" page
It used to say "notify me" or some such. Now it says "Update Me" and takes you to a separate page for the notification. Very minor change, maybe just website
reorganization. Amazing what we can read into little things when companies treat us like the proverbial mushroom. At least it still says "Spring"....
