This might not be the right crowd, but iCloud is really the un-clunky storage accessible from everywhere. It's just so well integrated between the phone, macbook, ipad, web. Worth it. I spend like $9-10 per month for 2TB of storage. with auto sync of my photos (which is where it really shines)
Yes, but that is assuming it is accessible everywhere. Majority in the world still do not have an fast enough wired connection.
Not sure if Apple is having some heavy hands in this but I think 4.9G and 5G will fix this within next 10 years. While it is still a little too early to tell, it does have the potential to be used as the sole connection in many areas.
The thing is I find my iCloud files are forming a canonical documents folder across my devices, whereas I always felt Dropbox was distinct from my documents folder.
