Frustrated by the mix and match of features between bodies

Thank you! I've looked at wifi cards which could be a decent solution for uploading to social networks except that I generally take raw photos. I could switch to raw + jpeg though. The 6D's wifi Android/iPhone app sounds very cool though. It transfers images downsized for uploading automatically and I believe it handles RAW as well. That gps module looks a little "iffy" based on the reviews. These might be my best options if the 70D doesn't implement the 6D's wifi and gps capabilities.
