It is still an age thing. Old people have far worse a time on trackpads, especially on Windows.
I think much of the problem with Windows is in the Synaptics driver. On one Windows machine, I see 5-10% CPU usage whenever my finger's touching the trackpad. The trackpad on that machine works a lot better on Linux. On the other hand, some other trackpads work far better on Windows than on Linux.
One big difference between trackpad behavior on Windows and OS X is that on OS X there's always delay between when your hand touches the trackpad and when the mouse starts moving -- the first N ms are ignored. On Windows, it varies from machine to machine -- for example, on an ASUS machine I have, you need a certain threshold of movement and then the pointer catches up to what its location would be, but with others there's no delay.
