Marcia,
I am addicted. I first heard about it in early spring - it's very popular in England. You can buy little paperback books full of puzzles at Heathrow. It keeps me entertained for hours at a time. After I finish my work on the plane, I alternate between Sudoku and knitting while traveling. It helps to keep me from going stir crazy during the long rides to Asia. Plus you can only make so many scarves....
