I'm planning on buying a macbook, and am definitely getting a extra mouse as I am not a big fan of trackpads, but it is inevitable that I will have to use the trackpad at some point, so my question is this; If a motion is made on the macbook's trackpad, the speed of that motion will affect the distance traveled by the cursor, i.e. if the same motion is faster the cursor will move further. I personally find this unpredictable and hard to judge. Is there a way to stop this and make cursor movement directly proportional to only the distance of the motion and not the speed of it? I realise the above is a tad wordy, but neither me nor the guy in the apple store could find an option for this, so I'd be grateful if anybody knows if this is possible. ta.
