I think it's just a question of what you can get used to. Personally I really like it, especially the two finger page scroll, which seems to work faultlessly (for me anyway). As for the zoom etc I haven't used it that much, set as standard it is a tad tempramental, but you can play with the sensitivity settings to fix that. The tap clicking is just a matter of individual taste I think. I like it, although I wish it could tell whether I was clicking on the left side of the touchpad or the right, and behave appropriately, but perhaps that's asking a bit much for now. Overall, no problems, does what it says on the tin!
