I'm curious. I'm not sure what patents are actually involved, but does anyone actually think that someone would buy a galaxy smartphone for tap to zoom? I bought my Galaxy S2 for the SAMOLED+ screen, Widgets and the notification center (which I didn't know was in the upcoming iOS but we all know apple ripped it from google). I don't give a rat's a** if it has tap to zoom, or anything like that.
I think that for the $500mil in lost profits apple would have to prove that people bought the phones and tablets for the specific features that they're talking about. Hard to do. As for the other 2bil...
I'm guessing the average Joe is more familiar with tap or pinch to zoom than they are SAMOLED+ screen.
