I currently have all my pictures on Dropbox, but there's really no need to have them synced between my laptop/computer at all times. In fact, there's really no need for me to have local access to them at all. While storage space is cheap, I run 2 VMs on my laptop and wouldn't mind freeing up a couple gigs. Plus, space on Dropbox is not unlimited...
Some googling suggests that Picasa is being rolled in with Google+ Photos. The neat feature here seems to be unlimited storage as long as I keep it to fewer than 2k x 2k pixels. I take pictures with my (Android) cell phone, so that works just fine for me. I have no intention to print them anyway.
However, one of the nice things of the Dropbox app is that it uploads pictures as soon as I take them. Once uploaded, they're obviously stored privately. Can I do the same thing with Google+ Photos?
It seems sharing pictures on Google+ is going to be a lot easier for the ones I do want to share, but I'd really want a default setting for newly uploaded pictures to be private until I add them to some public album.
