now, i'm no lawyer but I am a tech profesional and my interpretation of this patent is that the 770's virtual keyboard is prior art.

they spend a lot of time in that legaleese talking about things related to making sure parts of the application wanting input don't get covered by the virtual keyboard when it is triggered, as well as how to get rid of the keyboard in a way the user would seem to expect. With WinCE, I found that it often would either cover my input area or reduce the screen or input area to something not entirely unlike unsuable, sometimes the kb wouldn't come up when you thought it should, and didn't go away when you thought it should. With the 770 things are resized, new scroll bars appear, content is scrolled up to make sure the relevant area is visable, the kb comes up mostly when you think it should and never hangs around when you done with it. Seems exactly like what Apple is trying to parent here. Am I wrong?

IMO, this is just more evidence as to why software patents are a Bad Idea.
