Thanks a ton for the link, was looking for this site but couldn't remember the name.
I think my decision may be made. Performance wise the S4 and DNA are very similar in factory configuration. Where the S4 begins to pull away is:
Removable battery
SD card slot
13mp camera vs 8 in the DNA
I think the only downside I can find to the S4 is the 9.6 usable memory vs the 11.2 of the DNA, of course this is a non issue with the SD slot.
