New iphone camera certainly outdoes the z10, but i find the quality of the z10 pics pretty good.
In good light, outdoors or indoors, they're great. low light with no flash, they can be bit hit and miss.
Having said that, BB has made a lot of improvements to their software and algorithms and I'm sure the final 10.2 release will improve again.
I'm with Gerbick in that I love the Z10 but not enough to get a Z30...
