"Almost" being the key word. The 4 schtuff is more similar to the 2 than the 2 to the 1 anyway. Some report it is more responsive/quicker to open and such... but then some also claim better sound which is a bit far fetched. I was almost ready to try it out meself since the 2 on a 1 worked so well, but my current 2 ZS is trouble free and by some accounts the 4 software on it is not (although others seem content). I would be more keen if I could get an unmessed with 4 image and "hack" its setup and driver update setup myself rather than relying on kooky modded packages claiming to employ setup profiles for better game or music sound, etc.
