These reports are based on 2 rounds of usability studies with real users, reporting how they actually used a broad variety of iPad apps as well as websites accessed on the iPad.

Normally, it wouldn't be worth doing a new study this soon: usability guidelines change very slowly because they derive from human behavior, not technology. However, in this case, it's reasonable to conduct new research now, a year after the iPad launch.
