I've actually seen quite a few videos of the Hero in action. Personally, I don't see the "lag" as much of a problem. It's like that with every new platform and it has MASSIVE potential. And as someone formentioned(my apologies for not checking the poster before writing this), they can improve it with updates. My G1 has been lagging really, really, really bad the last couple of months. Also, I don't think Sprint will do anything to this phone, negatively, that is. As far as I know, they don't have a history of demoting phones' features.
