I think that the windows command shell kinda sucks, though I use a command line for a LOT of things on my win2k machine.
Check out Cygwin, if you're interested. It provides you with a Bash shell in Windows, using a layer of abstraction over the Win32 API, and also allows you to install many applications that would otherwise be restricted to linux.
You also get a lot of useful linux tools, such as tar, find, grep, gcc, make, etc...
