As stated just wanted to know if anyone has gone this route and whether or not it would be a worth while venture? A pro's and con's sort of thing. Generally if anyone has done what were the improvements for the money in a nutshell. Have a Z2 which was bought from the Ivojo pre-order and have been pretty happy with the perfomance o/all. Vertical banding had been an issue but firmware upgrade seemed to sort that out. Does Z3 suffer any of these type of problems or are they new/different problems. Have read some of the posts re the Z3 but wanted more of a direct comparison to the Z2 if possible. Also a little help in being pushed one way or another. Cheers, eatstatic. ........Or wait for z4?
