As far as touch goes on IOS I can't believe how many touch based gestures are missing from IOS. For example Safari try going forward or back a page on IOS. Can't do the nice one finger sweep to the right or left like OSX. No easy top sites either.
Not sure what you mean. You can swipe back and forward in Safari on both iOS and OSX. It works exactly the same on my Macbook touchpad as it does using the on-screen swipe on iOS. (except that you actually use two fingers on OSX). On iOS, you just swipe with one finger from the left or right of the screen. Top sites is easy to get to on both OSX and iOS. On OSX, you have a button in the menu bar. On iOS, you just hit the address bar.
