With the RTM release my dell bluetooth drivers really freaked out. systeminfo wouldn't pull up because the drivers failed, some things about bluetooth would work, others wouldn't. The solution is simple, reinstall the driver.
While waiting for the service pack is hard, and rather unfortunite, I think it is best to delay the release to the general public. I think Microsoft wants to avoid the press and users saying that SP1 FUBAR'd their machines because some drivers were improperly written. People are quick to criticize, Microsoft will never get praised for SP1, only ridiculed.
