I am surprised nobody has mentioned multi-monitor setups. This is where you really experience how bad the concept of a single unified menu bar for EVERYTHING that is running on the machine can be. Connect four 1920 x 1200 (or larger) monitors to your machine and you'll be cursing in no time at all. Even a simpler dual screen setup suffers from this concept. I don't care if it is under osx Or Ubuntu/Unity, this UI is inferior to one where the application and the relevant menu exist in a self contained window. Now, that does not mean that an application cannot spawn multiple windows at all. For example, Altium Designer --a high-end electronics circuit design package-- can make use of one or more monitors quite effectively. You can, for example, have the schematic editor running in a window on one monitor while you design the PCB on the second and the documentation is open on the third. Each window houses the relevant menus and toolbars. This would be an absolute nightmare on OSX or Ubuntu style single menu systems. It doesn't end there. If I am working on a web project i might have my IDE open front and center while supporting tools are open on the other monitors. I usually run several virtual machines on the monitor immediately to the left. Each machine runs a different browser for testing purposes. I found this to be far easier than other options and I can keep those virtual machines and browsers clean of extraneous stuff that might otherwise modify behavior. I then keep a terminal window or two logged into whatever remote server I might be working on. This can also be on a separate monitor if needed. I usually keep the terminal on the left with the VM's. On my right monitor I usually run Chrome and Firefox for reference (PDF's, manuals, SO, etc.) and technical debugging purposes. If needed other tools such as email and the too-important music player go on the right as well. If I need photoshop, excel or some other tool it usually goes in the center monitor. I tend to keep several open file browsers on the fourth monitor (although Only one of my systems has four large monitors). Again, dedicated and context-appropriate menus make it easy to deal with such a setup without having to mouse all over the universe of available pixels. If I had to do this on OSX or Ubuntu I'd probably throw the computer out the window. In fact our Mac systems all have dual monitors but I still use the Windows systems for almost anything other than iOS development because OSX continues to evolve into a royal pain in the ass. I can run Ubuntu 12.04 LTS server in a virtual machine on the PC with a shared drive and have the best of all worlds. BTW, running Vista and 7.
