PowerShell - Special Folders (System Folders)

In VBscript, there existed a concept known as Special Folders, for example, My Documents which could be accessed using the Shell. Application object and passing in a constant that applied to a certain folder. This is also possible using PowerShell.

$a = New-Object -ComObject Shell.Application
Get-ChildItem $a.NameSpace(0x21).Self.Path

The prior two lines of code can also be written as follows: 

Get-ChildItem ((New-Object -ComObject Shell.Application).Namespace(0x21).Self.Path)

Below is the list of special folders and its hex number, please do comment on this post if any of them is/are wrong:
