Should TempDB be on its own drive?

By default, the TempDB files are put on the same drive as the SQL Server binaries. Even if the user chooses a custom install, TempDB still goes on the same drive as the other data files, and that's not a good idea either. Instead, the TempDB data files should be on their own dedicated drive.
