I never thought I needed a cordless iron but having it has made such a huge difference.  I especially love it for things like bed linens where you can reach the middle of the bed with absolute ease.  I have also used it on curtains and found it to be so much easier to use than my steamer.  I don't think I can ever go back to a corded iron.  The only thing is I wish it would get a little bit hotter.
