Yes, I don't think the author has thought much about these kinds of issues.

Two particular nitpicks that come to my mind are reverse scrolling and automatic termination. Reverse scrolling -- drag down to scroll up -- may be natural on a touchscreen, but why bring it to the PC and switch away from the way you had done it before (and everyone else does it)? Automatic termination -- shutting down apps in the background without asking you -- also makes sense on a mobile device, but is just a bad idea for computers.

By themselves, these kinds of things don't mean much, but these sorts of decisions and some coming mntn lion "feautures" seem to show a pretty clear trend of bringing mobile-inspired features to OS X, regardless of whether they make sense in that context.
