I know of a very large company that has been over the last couple of years moving from Java to Flash, so it will be amusing to what their reaction will be to this news.
Supposedly upgrading the vSphere web interface to HTML5 is on the roadmap, but I'm not sure when. I'm just happy that they give you an external console app now.
Now that we're down to the last few sites running flash it really drives home what an annoyance they are. I don't run flash on my main browser (I work in security), so I have to keep Chrome handy to log into VMWare, and because even the login page is Flash there's little password manager support.
Then once I'm logged in the non-native styling and controls really drive me up the wall.
VMWare is one large one.
