Umm.... actually, the O/S I work 90% of my time on is CentOS, and typically the minimal install (what is this shell "window" of which you speak???), so I'm fairly familiar with these mystical and obscure symbols that you mention.... lol... I use Windows 7 in a VM for pretty much my work Exchange account, Office, and Visio. Not quite sure why you are jumping to these conclusions merely because I actually use Windows.
