Quite so, Dunk. My Samsung monitor relied on a a battery-driven stylus; it needed an hour's recharge for every three hours usage, and during that last hour the cursor shot all over the screen (it always happened when in the middle of a very tricky illustration).
I thought my Intuos 3 was having the same problems (jerky cursor) until I realised my wireless keyboard and mouse could sometimes run interference.
I enjoy the Intuos 3 because of the way you can almost handle it as a drawing pad (and the large drawing surface). The lead is very long, and depending how well I feel when drawing (I have a bad back, disposition towards RSI AND chronic fatigue), I can either lean back and position it at an angle against the desk's lip, or slump over it flat with the desk. The keyboard shortcuts mean I can leave the keyboard stored under the monitor out of the way, and the stylus practically replaces the mouse.
