I just wish the iOS client didn’t scroll entire pages at once. I naturally scroll whatever I’m reading to the upper or middle part of the screen. Do that with Feedly and the whole page of items scrolls up. Minor annoyance.
I’m quite happy that neither the Chrome desktop version nor the iOS version have asked me to verify my credentials in a while. That was getting obnoxious.
But I wouldn’t trust iCloud to be around long enough to make it my primary account. You know how Apple has no reservations about dropping things. (I love Apple, but you never know when your product or service will fall to their whim.)
