May I add to this thread - it's entirely down to the change, but how you use it on Windows 8.
If I take a photo on my ipad or iphone, it shows on either device.
But I have iCloud on my laptop, yet it's completely confusing.
Whereas we use to see it all in My Photo Stream - upload to there and it appears on devices. Now, you have Uploads, Shared and My Photo Stream. And in the ICloud software link, you have Activity as well.
So it's gone from ONE folder, two FOUR.
The confusing begins here really. If I upload a file to Uploads, it appears on both devices. If I delete it from Uploads, it remains on both devices. If I delete from the devices, it remains on Uploads.
My Photo Stream - I don't know what that is for anymore. It shows only old photos - nothing that is newly taken or uploaded.
Activity - that shows photos I took at the weekend, but isnt showing anything I took as a screenshot on my ipad.
So while all the positivity surrounding it made it appear like they have needed this for years, it's completely cocked up all understanding of how it worked, and I Want to know how you use it effectively. How you avoid double storage use (my photo stream and uploads for example), and how you find a photo in iCloud on your PC, to drag and copy to PC for backup use.
During iOS7, I knew how. In iOS8, I haven't the foggiest!
