The new trackpad is less intuitive than foreseen

Many people on the web have found that the new trackpad on the new portables can in certain cases pose problems.
To start with, it happens that the click is ignored. This is especially the case if one lets trail on the surface many fingers or part of his palm. For others, the problem seems with something already known in the past. There is a time lag of a few second to take into account the actions. But more aggravating certainly is the function of zoom which can be activated by anything, for example while scrolling a page of safari one gets a sudden enlarging of the fonts.
In fact, a feature that one misses more with this trackpad, is the ability to more finely configure it, using the System Preferences.
PS: Anyone who finds how to deactivate the zoom under Safari will have my eternal gratitude.
