I wish that they'd aliased the old DOS "ver" command to Powershell's Get-Host command.
If you type "alias" at the Powershell command prompt you'll see a ton of aliases that they've setup. "dir", "copy", "cls", "compare", "md", "cd" etc. These greatly ease the transition to Powerhsell's commands if you want to quickly drop in to a command prompt and have a PowerDOS environment.
I know that I can easily configure Powershell to alias "ver" but the only time I usually need this is when I'm on a new machine and don't know what version is running. After that I don't need it anymore. Even "Get-Ver" would be more helpful and logical than Get-Host.
Anyway, if you haven't figured it out by now:
ver = Get-Host
