Yes. This constant urge to remove any browser chrome possible is getting more and more irritating. It's basically a textbook UI anti-pattern that some fool thinks is a good idea and some other fools are copying.
I have a nice, large monitor that runs at a nice, high resolution. In fact, I have several. Not even my laptops are short of screen space these days. Some of this is high-end kit, but entry-level monitors are widescreen and run at decent resolutions these days too.
Space for an extra icon in a consistent position is nothing in this context. However, the irritation from having UI elements or page content move around under-cursor is significant, and the irritation from having to click multiple times or click-and-hold to access functions that used to be one-click is also great, particularly if you first have to guess which of the entirely meaningless icon thingies might hide the secret menu with the item you're looking for, or remember which browser you're using so you know whether the icon you want is on the left or the right of the other unlabelled random icon thingies and whichever text box bar thingies we're drawing this week.
I'm all for innovation, but we have platform UI standards for a reason. Breaking them because you think your software is more important than everyone else's isn't clever. Being the company that also makes the OS and wrote the platform UI standards is no excuse, either.
I think we have two groups of people to blame for this phenomenon:
(A) "Novices" who get confused when presented with more than a handful of buttons, because they never bother to figure out what those buttons do. BTW, what's a browser? You mean Google? No, I use Bing.
(B) "Experts" who don't care whether or not there are buttons in the UI, because they know where everything is hidden, and they use keyboard shortcuts anyway. Meanwhile, everything Apple does must be the One True Way.
When Group B makes software for Group A, you get the results you're describing. Caught in the middle are a large number of moderately proficient users who rely on explicit visual cues (buttons, arrows, menus) to perform tasks.
