I got through about the first five, came up with five rebuttals to what he said, then stopped.
1. This is good. It means that you can't accidentally wake a computer by bumping the table and having the mouse move. Unfortunately, this doesn't work on older Macintosh computers that don't support deep sleep -- like mine. Moving the mouse wakes the computer, as does clicking any button, be it keyboard or mouse.
2. An ellipsis means that a dialog box or confirmation box will be presented before the action is carried out. "Open Location..." means focus switches to the location bar, then the user must type the new location. If the ellipsis weren't there, then it would mean automatically open a new location. "Downloads" mean just that -- you are presented with your downloads without further input required. Seems pretty consistent to me.
3. Big deal. A few pixels. Who hits the File menu without actually looking? Besides, the menus are different for all applications. Some have a "Bookmarks" menu, some don't. In that respect, the menubar items are in different places for every application -- same as in Windows.
4. So what? The brushel metal appearance, IMO, is there for applications that resemble real-life appliances, like iTunes (your stereo), Quicktime (your DVD player/media player), iPhoto (your photo album), Safari (your TV), Calculator (if you can't figure this one out, God help your soul), iCal (your desktop calendar). While there are exceptions, they are few, and Tiger should standardize the brushed-metal appearance more.
5. It's always been like this... you don't EVER need to delete text when selecting a search box if you tab to the box. If you're still the kind of person that clicks in a text box, then holds down backspace until everything's gone, then types the new text, you need to take some classes on using computers (double-click for word, triple-click for entire box). Besides, text that disappears when the box is selected (like "Google" in Safari's search bar) automatically disappears, and is colored gray. Text that needs deleting (user-inputted text) is colored black.
6. I got nothing here. It is damn slow in OS X.
7. I got no rebuttal here -- I've never had a problem discerning the two.
8. With one big difference: they're not on a button.
9. Bah.
10. Nope, sure doesn't. Bug report.
11. Dragging to the menubar would be a counter-intuitive way of cancelling a drag, even though it does work -- simply because you can't place an icon on or under the menubar, so that's why the drag doesn't work.
12. Sometimes this bugs me, but it doesn't slow me down.
Ack... that's all I can come up with now. He's got some good points, but it seems rather nit-picky. 'A' for effort.
