PowerShell comes with a number of canned aliases attempting to help the author make typing easier. For example, running Gwmi takes less time than typing Get-Wmiobject. This is a definite Unix mentality that values speedy typing over clarity or easy-to-read script. However, speedy typing does save time. Also, if you're just using the shell interactively, there's little reason to care what anyone else thinks about how clear or easy-to-read your script is!
