I think some here would be surprised to see how fast an experienced POSIX user can navigate the shell. If you use ls and grep all day, everyday, you can enter those specific key-combinations amazingly fast. It would be slower to type a less familiar word, such as sizeof.
If it is just the size you want, ls, grep, and cut can make it happen. The real show-stopping reason for POSIX systems not having a specific utility for this is that there is a command called alias. ;)
Now I have to do what most companies do when people say there's something better than their program: add a bunch of features that have no relevance to the program itself.
Let's see... a Master Boot Record editor should give me the edge over ls. And maybe functionality for monitoring the movements of sharks via satellites and microchips embedded into the shark's dorsal fin...
typing in Dvorak is faster than typing in Qwerty
That's like saying that using the command line is faster than the GUI. It isn't if you don't know how.
Oh, wait. I just destroyed my own argument...
Also, who boots explorer from the start menu? Don't you have shortcuts to common directories in the launcher on your taskbar? Do you at least have a cmd shortcut since you appreantly use it a lot? Or do you actually go to Run every time?
I don't know if you saw, but I replied saying I would show you my toolbars in GNOME... well here is what they look like right now: http://i46.tinypic.com/2dm5vmf.png
I originally used Xfce in Arch but I went back to GNOME because Xfce doesn't have a few features I think every desktop environment should have; and I think GNOME is a bit more intuitive. Anyway, I switched back to GNOME. I still have Xfce though, I cba to remove it.
If you're wondering what the big space in one of my toolbars is, it's so that the window list doesn't expand too far and take up the whole toolbar. When that happens, you can't change the properties of the toolbar, so from now on, I have that little bit of space set aside. I would do it for the toolbar at the top, too, but I don't think I need to because I'm unlikely to fill that with icons.
Ah. In GNOME right now I have controls set to Glossy, Window Border set to Clearlooks, Icons set to Mist (sometimes I change them to Tango or Oxygen) and my pointer is Oxygen White.
