With the iPad you don't need Flash, because every web site works with it. Every web site has implemented video in a superior way so as not to need a crutch.

With Tom's Android phone, the web site wants to use Flash but can't because it's not available for the phone. The web site however thinks that there's already some version of Flash installed as reported by the "upgrade required" error. Someone needs to tell those web masters that Tom's phone also doesn't need a crutch.
