Are you a Windows command-prompt power user? Console is nice tool that sits on top of the windows command-prompt and adds some funky features and eye-candy; for starters, I love to see the wallpaper in the background rather than a plain colour. Then, there are tabs and transparency options!
And couple it with Cygwin to get all the *nix commands you’ve got used to. Btw, if you have already toyed around with the new Microsoft PowerShell, do let us know what you thought of it! Original recommendation for Console based on this LifeHacker post. It also has an interesting introduction to Cygwin.
