The conventional end-of-line hotkey for Windows applications is the End key, which on a fairly traditional keyboard like the one I am typing this on requires that my right hand move several inches to the right and find that key on the island; I can't touch type this effectively and it compares poorly to C-e or even $ (itself not especially a convenient operation). Gnome and the Mac don't have this problem because both of them largely retain the simpler Emacs style keystrokes; Firefox does have this problem (at least here) and it pisses me off every time.
