It came first, and
joyetech was trying to simplify the
mod after the original Evic, where they heard that customers didn't use the many features they provided.
Of course, as soon as it was released, the biggest complaint was that the chipset was upgradable via USB. {facepalm}
At this point in time, I do not know if
joyetech will release a V2 of the Evic VT with the newer, upgradable chipset.
