> Their purpose is to convey information in limited space. No, that's only one of their purposes. Another one is faster visual parsing of shape recognition instead of reading even if space is not an issue (just like with all of these menus, they waste so much space on padding they could fit command names 3 more times)
Yes, and as much as I hate to defend modern UI designers, I believe the icons in the menus here are actually extremely helpful (even when duplicated). In the first example, when I want to find the option to add or delete a row in this massive menu, the icons clearly convey the purpose. I can instantly filter a huge list of possibilities down to a few relevant entries.
X, volume & mute icon, disk icon, upload/download icon -- these are all fine and good; you don't need to spell those out for me because their use is so widespread that even if I didn't know what they meant, it'd be very useful to learn. I have no idea what a generic "integrated circuit" icon means, though, and I doubt anyone will use it elsewhere to mean the same thing, so I just click around randomly until I find what I'm looking for, like I'd do with the previously-unlabeled 6-switch panel in my living room where the positioning of the switches have no obvious relation to the physical placement of the ceiling lights.
I think Apple's menu actually shows exactly what I want and expect; show icons if it'll help me, don't show them if they wouldn't; though in come cases, I think Apple could apply some more icons (like for "Stop", there are a few good choices for that).
