I use Win 7 and Chrome browser. A few months ago, I uninstalled ALL Adobe stuff, including the ones you mentioned -- and Silverlight as well. And for good measure, I also uninstalled Java.
Most all animation and video I encounter are from websites. My Google Chrome browser includes an Adobe Flash plug in. Thus far, I haven't encountered any video that couldn't be played. So no need for installation of a separate Flash app. I don't miss Java or Silverlight at all. Your web experience may differ.
But off the web, some apps depend on third-party animation apps. My 'Encyclopaedia Britannica' DVD requires Adobe Shockwave. As well, I just made a purchase of the National Geographic DVD set. I haven't received it yet, but I believe it will require Adobe Flash -- in which case, I will have to re-install it.
As you can see, it all depends on where you browse and what apps you use. Hopefully this helps.
