Ally,
Sorry my first reply was so vague. I can't think of anything you can do with cakewalk that you can't already do with what you have. It's a different means to the same end.
It probably is easier to edit if you need to, with a large screen, but not necessary.
If you have a specific question about a feature in Cakewalk, You should post it in the Cakewalk Forum, where there are many experts to help you.
