With the release of the Nexus 7 tablet, Google has has the attention of the media and the users that is normally reserved for Apple products, and like Apple, has had to deal with unreal amounts of popularity for their tablet.
Unfortunately they didn't deal with it gracefully, and they're very much leaving users in the dark as to when their pre ordered units will ship, and even after letting users pre order, they are not shipping to many people until well after the Nexus 7 is available on store shelves.
This situation mis management is going to cost Google a lot of good will unless they're willing to eat a few dollars per slighted user and issue freebies via the Play store...
... Which they seem to have no intention of doing.
