Question: Opening the command prompt ("cmd") on Vista into full screen causes the application to take up 100% vertical space, but only about 50% horizontal. Is there not a way I can make this fullscreen? If it's simply not possible, what is a good replacement?

Answer: 
Found this trick somewhere on "The Internet".

1. Open cmd
2. type wmic.
3. Double click the bar to maximize the screen.
4. Type exit and press Enter.
[This](http://www.walkernews.net/2007/06/03/how-to-maximize-vista-command-prompt-window/) article explains how to do it in Vista

In short you need to specify the screen resolution manually in the Display Options.

Replacement? [Powershell](http://www.microsoft.com/windowsserver2003/technologies/management/powershell/default.mspx) of course.
