Am thinking of it cos i have some sensitive documents i want to keep out of prying eyes and i have never used one before... Anyone using one now? Am interested to find out the CONS of using it. And is there really a "ghosting" (3D) effect (this is indeed a deal-breaker) on the homescreen icons i saw in some youtube vids... Power Support has a 4-way one. What's the difference between the normal 2-way and the 4-way? Sorry to be asking this, but there are too few people using it.
