at some point in math you'll never use x for times/multiplication -- you'll always use a dot, unless you're specifically doing a cross product. And that is a good stage to reach. (I still have trouble using x for multiplication though.)

(Also, the cross product is always a less elegant alternative to the exterior product, but I guess this isn't the place for that rant.)
