However, OS's are capable and do differentiate from laptops and desktops. Windows 7 does not have battery options or gauge when there is no battery.
The question becomes, and it's a philosophical one, "When and where is this worth doing?"
I would say that since Airplane Mode is directly related to WiFi, that its actual function is to shut down WiFi temporarily, and that the desire to do this exists on every platform, including desktops, that this is not something that one would wish to disable or stipple out on a desktop.
People understand what airplane mode is about, even if they're not on an airplane, so I really prefer that I have it available on my desktop, too.
