> The author makes a big deal of lack of snapping. Frankly I've never seen the utility of it on OS's that do have it, infact I've always felt it more of a hinderance than a help (gets in the way, tries to snap when you don't want it to).

It may be useful for users of large external monitors, allowing to make better use of the screen real estate. Then again, Macos lacks per-application menu bars, which means you cannot do a lot of tasks without focusing the app first, so IMHO lack of snapping/advanced windows management is not as big as a deal as it would be under Windows.
