Uh of course, what is there not to like? It stores your Desktop and Documents folders in iCloud. It doesn't interfere with normal use. Also couldn't be happier with iCloud Photo Library, it does exactly what its supposed to do: Stores all photo and video in the cloud, automatically. Every device can access. Devices with more storage can keep local copies. Devices with less storage can brilliantly optimize and still have access. Could not be better.
I find people typically have their own niche ideas that make very little real world sense, and would adversely affect the experience for 90% of users, are often the ones "unhappy" with perfectly executed features.
