I'm surprised no camera manufacturer has created an easy way to get all your photos to Google Photos / iCloud/ Dropbox / etc. They have some wireless photo transfer things, but they're clunky and unusable. Just connect the camera to WiFi and auto-upload everything to the service of my choice. I'm guessing it's a mix of:
* Camera manufacturers are hardware companies and can't do software and cloud stuff.
* It wouldn't interact well with swapping SD cards, which is what all the pros want.
* The camera would need to stay powered when off to upload photos. Current cameras have a hard power switch.
