The part about Photosmith mentions the Camera Kit, but I assume that since Photosmith syncs from the Camera Roll too, then the combination of an Eye-Fi card + Photosmith + Lightroom is a a godsend.
I see you used Filterstorm a lot. I have several photo apps, including most you mentioned like Snapseed, PhotoForge2, Photogene2, Luminance and others. Would you recommend me Filterstom in addition...
