Just found out that you can enable multitouch on any laptop with a synaptics touchpad by swapping out whatever brand drivers you have for the hp envy drivers. i have my 2 finger scroll and pinch to zoom back for my alienware and i love it.
Step 1: Uninstall Current touchpad driver (if you arent using 7 then you may need a mouse to do the next steps)
Step 2: Go to HP.com and download the touchpad drivers for the HP envy 14 inch, Note, the synaptics drivers from the website will not install over current drivers because they show up as being older.
Step 3: Install the Hp Drivers
Step 4: change multitouch to on in the mouse settings in control panel
Step 5: ????
Step 6: Profit
