It is jarring at first, you have to remind yourself that this is not a desktop. The weakness is there is no such thing as a hover.
We need to treat mouse input as an extension of our finger, and I think once the muscle memory is developed (using the mouse to swipe from the edge, or to drag the dock instead of hover) it is not really different from a desktop mouse.
Plus I think where the mouse lacks, the brevity of keyboard shortcuts can compensate, especially in text editing. Keyboard shortcuts are more than enough to get you writing well on the iPad, except if you want to place the cursor exactly where you want without touching the screen. That is where the mouse really helps.
