Siri and Google voice actions do quite a bit more than dial people in your address book. In fact, they are probably worse at that than at other tasks because name pronunciation is difficult. I'd suggest looking at some demos. As for your latter two points, yes, people may think you are silly if you speak to your phone in company. Also, background noise such as people next to you speaking can really confuse these systems. However, I've used it many times (the google version) to write short text messages and most of all to ask for directions. Why? Because it's much faster thank keying in all that information, especially for directions to intersections or restaurants. For the latter, the system gives a huge added bonus in that it will actually look up addresses for you just based on a store name. Siri gives one extra feature over google voice actions as well: speaking back and context. While speaking back may be somewhat of a gimmick, there are lots of ways to report information, using the previous action to fill in contextual information in the current action looks to be quite useful.
