Today I wanted to watch some of the streams from Google I/O Live, which as you would expect are hosted by YouTube. I have full Chrome installed into my Sputnik image, but it did not have support for Flash.. so no video would play.
I realized that the base Sputnik image came with Chromium, and I installed full Chrome before removing Chromium, which did not provide the full set of plugins.
So, a quick re-install of Chrome (apt-get install google-chrome-stable) and now all is well.
So, if anyone else out there attempts to use the base Sputnik image, beware of Chromium. Barton, if you all refresh that image, please include full Chrome.
