The replies in this thread are confusing. So many seem to be comparing the VR shots to what they would have been with a tripod. I understood the comparison to be between shots taken with a lens with VR vs one without. Assuming I'm interpreting the OPs post correctly I think the tripod comments and discussion are irrelevant. I haven't read all of the replies but I suspect even the OP would agree that a tripod would have produced better results.
And whether the OPs examples are noisy, not sharp enough, not interesting, etc doesn't really matter as they do show improvements over what the results would have been without VR (and without a tripod...). With a little imagination you should be able to determine what VR could do for you..... don't like the noise at ISO6400 then don't use ISO6400.... don't think 1/6 with VR is fast enough then don't shoot at 1/6. VR is a tool just like the other hundreds of tools we use, you decide when it works for you. Shoot 100% on a tripod and we can all agree you will never need VR
