Federico Viticci's annual iOS review at Mac Stories praises iOS 27 for showing Apple "still capable of delivering something new while caring about the old." While not as "flashy" as last year, the update demonstrates renewed attention to detail.

On Apple Intelligence and Siri AI, Viticci notes the new Siri isn't an agentic product capable of long-running tasks like Chat GPT Work, Claude Cowork, Grok Bot, Hermes Agent, or Open Claw. He appreciates Siri AI as "a much better, smarter Siri that doesn't aim to replace your favorite agent (yet)" and finds it best for quick, one-off interactions with apps like Apple Notes, Reminders, HomeKit, Ask Play, Monologue, Alyx, Music Box, and Look Up. For deeper research, he falls back to Chat GPT or Open Minis for iOS.

Viticci's review meticulously covers every iOS 27 detail. John Voorhees also wrote the macOS 27 Golden Gate and watchOS 27 reviews. Club Mac Stories membership unlocks extras, and 9to5Mac offers additional iOS 27 coverage including feature roundups, how-tos, and guides.
