Haha @ frankie, And just to put my 2 cents worth in, or dimes worth, i use an orbital to remove large blemishes and machine marks, then work up the grades to your desired finish. An awesome painters trick is to shine a strong light at a very low angle across the surface you are sanding. It will show up every tiny blemish, even orbital sander swirl marks.. Fantastic for when final finish is high gloss.
