I don't know if you mentioned scrollbars as a rhetorical argument, or literally. But if the latter, then ... (queue rant) ... What? Even scrollbars? Shows just how broken, regressive and anti-innovation the US Patent system is. Its part of software legend how Jobs et al learned of these concepts through early exposure to Smalltalk. There are numerous videos of Jobs himself talking about it (with requisite amounts of awe). I'm sure most people here already know the history. Theres even the interesting tale of how Jobs critiqued the scrolling (he prefered something smoother than line-by-line scrolling), and Dan Ingalls live coded a solution in a few minutes. "Prior art" indeed :)
