Wacoms use a pretty natural hand-eye coordination that your brain is wired for. Styuli have been used by humans for a few millenia now with no real issues, until one prominent human decided he didn't "want a little scribble thing" and subsequently wiped out the market for them. If you're using touchpads, going from touchpad to stylus is exactly the same switch as going from finger paint to pen. If you're using a mouse, then using a stylus allows for less awkward wrist motion. Absolute positioning is AWESOME for static or mostly static UI elements: menu bars, browser tabs, buttons on websites since your brain can calculate 'ahead of time' how much it needs to move. It's also much more accurate when performing small motor movements (hence why it's used for drawing, but this also comes in to play for highlighting text). It does not perform as well when scrolling, which is where relative positioning works better.
