I don't consider computerized quilting cheating at all. I don't see any difference between following a board with a stylus or a computerized pattern; is the board/stylus much different than a paper patten or stencil and stitch regulator?
There is no such thing as a machine that will quilt all on its own; each top is different in the accuracy of piecing, straightness of borders, etc. and every bit of that requires skill and experience to deal with in order to have a quilt come off the frame looking as good as possible. There is a lot more to long arm quilting than pushing a machine around, just as there is a lot more to piecing than slapping a couple of pieces of fabric together.
Then there is economics; are we willing to pay appropriately for the artistry many long arm quilters provide? A lot of times, the answer to that is 'no' - I hear many complaints about the high cost of having a quilt done. All-over quilting is less expensive, yes; but I wouldn't want to stand there day after day doing it over and over. ;)
