Interesting thread. I'm no longer "popular enough" to have encountered the problems noted above, but as mbooty points out, this is a major problem for those trying to use a droid in many business environments. (And unfortunately, it's another indication of the reason that so many business users will give up their Blackberries when they're pried out of their cold dead hands.) No solution from here but I would point out that Google Voice provides some features in the form of contact group specific and number specific voice mail messages that may help at least alert specific callers with a personalized greeting. The feature that allows one to screen incoming Google voice mails may also help in specific situations. Somewhat off the central point here but I've always been annoyed by call waiting features that prioritize an incoming call above a current call. They remind me of a situation where I take the time and effort to go to a store and have a clerk suspend our conversation to answer the phone. IMHO it's usually better to deal with demands in a first come/first serve manner. But I realize that's not a rigid rule.
