I really don't understand why there is all this song & dance about this magical new service. I've had all my photos uploaded to Picasa Web Albums for years, these photos were also visible through Google+ Photos and now all they've done is split Google+ Photos into it's own URL (https://photos.google.com).
From the Android side, my photos were automatically uploaded and you could select to have them compressed if you didn't want them to take up your storage allowance. I pay $5 a year for 20GB (a legacy deal that I get to keep as long as the payment never fails) plus through various offers have a total around 100GB available so I upload full size.
Picasa Web Albums is still available and offered easier organisation of photos than G+ Photos. I had to switch to G+ Photos in Chrome in order to edit the photos though. In addition to this, the photos are also visible through Google Drive.
_I_ want to decide what constitutes an album not some algorithm. Also, I would like to tag people in my photos without an email being sent to them and the photo automatically being shared with them, so that I can keep track of who is in which photo, something that was available in the Picasa desktop software but I haven't used that for years.
So what's new?
Edit: The article mentions 1TB, implying that is the lowest paid tier offered, but you can get 100GB for $1.99/month.
