a one-liner I also like :
a GUI directory copy :
(new-object -com Shell.application).NameSpace((new-object -com Shell.application).browseforFolder(0, "Select Target", 0, 0x11)).CopyHere((new-object -com Shell.application).browseforFolder(0,"Select Source", 0, 0x11))

Here's some from my blog (and from daily use):
If you are thinking about adding more RAM and can't remember how your current memory occupies banks:
PoSH> get-WMIObject Win32_PhysicalMemory |
>> select DeviceLocator, Capacity, Speed | sort DeviceLocator | ft -auto
>>
DeviceLocator Capacity Speed
------------- -------- -----
CHANNEL A DIMM 0 536870912 400
CHANNEL A DIMM 1 536870912 400
CHANNEL B DIMM 0 1073741824 400
For developers:
# Show me all the versions of the MS CRT loaded and what processes
# are using them.
PoSH> get-process | select processname -expand Modules -ea SilentlyContinue |
>> where {$_.ModuleName -like "msvc*.dll"} |
>> group {$_.ModuleName} | format-list
Name : MSVCP71.dll
Count : 12
Group : {CCAPP, CCEVTMGR, CCSETMGR, EDICT, iexplore, msimn, msn, NAVAPSVC,
NPFMNTOR, SPBBCSvc, WeatherDataClient, WINWORD}
Values : {MSVCP71.dll}
<snip>
Stats on your music collection:
PoSH> gci "$home\my documents\my music" -rec |
>> where {!$_.PSIsContainer -and $_.Extension -match "wma|mp3"} |
>> Measure-Object -property length -sum -min -max -ave
>>
Count : 1018
Average : 2991362.43123772
Sum : 3045206955
Max : 102750941
Min : 89025
Property : Length
And two simple ones that I like:
PoSH> gci | group extension | sort count
PoSH> gci | sort extension | ft -groupby extension
And to see when during the day you use the shell the most:
get-history -count $MaximumHistoryCount |
group {$_.StartExecutionTime.Hour} |
sort Count -desc |
format-table Count,@{l="Hour";e={$_.Name}},Group -auto
Here's one I used recently after I recovered files onto a new hard drive. It tells you which files have changed within a certain period of time.
$startDate = (get-date).AddDays(-3) # Get date for 3 days previous to today
gci . -rec | where {$_.LastWriteTime -gt $startDate}
Finally, dumping system event log errors:
get-eventlog system | where {$_.EntryType -eq "Error"} | fl
