For anyone who relies heavily on their phone for both work and personal tasks, iOS is a great option with its seamless integration and intuitive interface. Several G2 users appreciate how Apple continues to refine the user experience without overcomplicating things.
iOS 18 has been well-received for its polished experience and thoughtfully designed features. According to user feedback, the update reflects Apple’s continued focus on usability and innovation, with changes that feel intentional rather than purely cosmetic.
Whether it's for staying organized, connected, or entertained, many users find that iOS 18 helps streamline everyday interactions, making common tasks feel more efficient and intuitive across the board.
One of the standout features I read a lot of reviews about was the interactive widgets. These aren’t just static blocks of information anymore—you can interact with them directly from the home or lock screen.
G2 reviewers use them to check off tasks in their reminders, control smart home devices, and even respond to messages without opening the apps. It might seem like a minor upgrade, but it cuts down on the constant app-hopping that eats into productivity.
The upgraded Spotlight search in iOS 18 is frequently highlighted as a major improvement. Users describe it as faster, more intuitive, and significantly more powerful than previous versions. It now delivers real-time results across apps, documents, and web suggestions, while also adapting to individual usage patterns over time.
Functionality has been streamlined as well. Reviewers appreciate how Spotlight now integrates actions directly into search results, allowing them to start a timer, send a message, or launch an app without extra steps. Tasks that once required digging through menus, like locating an old email attachment or a rarely used app, are now quicker and more seamless.
The new Journal app in iOS 18 has received positive attention for its thoughtful use of on-device intelligence. According to user feedback, it suggests meaningful moments to reflect on, like recent photos, locations visited, or frequently played songs, making it easier to capture personal highlights without actively documenting everything. Reviewers appreciate that it feels personalized yet unobtrusive, offering value even during busy days.
Expanded sharing options are another area where iOS 18 shines. AirDrop remains a reliable favorite, but the addition of NameDrop has made contact sharing even more seamless. Users highlight the convenience of simply bringing two iPhones close together to exchange details, no typing or scanning required. It’s small touches like this that contribute to iOS’s reputation for thoughtful design.
However, the update isn’t without its challenges. Some users have noted that certain older apps don’t yet integrate smoothly with the new interactive widgets or Spotlight enhancements. While this is expected to improve as developers update their apps, it can cause minor disruptions for those who rely on legacy tools.
Storage requirements are another common concern. The iOS 18 system update takes up a notable amount of space, which presents issues for users on older iPhones with limited capacity. Several reviewers mention needing to delete files or apps to make room for the upgrade.

Many mention successfully using popular productivity apps like Microsoft Word, Slack, and Zoom with overall performance described as smooth and intuitive—though some note that not all apps are fully optimized for ChromeOS.
Speed and simplicity are also recurring highlights. Reviewers often point out that ChromeOS boots quickly, handles automatic updates in the background, and maintains consistent performance even after extended use. It’s seen as a hassle-free option for users who want to get to work without dealing with driver issues or system clutter.
However, connectivity remains a common limitation. The OS performs best with a stable internet connection, and while apps like Google Docs offer offline functionality, users note that the experience can feel limited in low-connectivity environments.
Local file management is another area where ChromeOS falls short for some. Compared to traditional operating systems, users describe the file handling as somewhat clunky—especially for those who work with larger files or prefer more hands-on control of local storage.
Lastly, while Chrome OS now supports Linux and Parallels Desktop for running Windows apps, these features are more suited for advanced users. Setting up Linux isn’t as user-friendly too, and the performance of Windows apps via Parallels can be a hit or miss.
“ChromeOS is Google's cloud-connected desktop operating system (OS). The web-app-focused OS powers mostly inexpensive Chromebooks—low-cost laptops for people with basic computing needs. ChromeOS is excellent for education and light productivity because it's easy to use with tie-ins to Google's online apps.
Android app compatibility enables access to millions of new software choices, too, though the implementation isn't perfect. ChromeOS isn't as powerful or functional as Windows 11 or macOS Sequoia, our Editors' Choice winners for desktop OSes. However, it's still a worthwhile choice if you prefer a simpler and more streamlined experience.”
- Chrome OS Review, Wasim A.
“It is not for professional usage. If you are a university student who has to install many high-performing tools such as Android Studio, VS code, and Unity, you can not work with Chrome OS. The same goes for working professionals.”

RHEL’s support for automation is another area that draws attention. Tools like Ansible are commonly used to simplify repetitive tasks such as updates and system configuration. Even without hands-on setup, feedback from IT professionals points to significant time savings when managing large-scale environments.
However, RHEL isn’t for everyone. The learning curve can feel steep for someone coming from user-friendly operating systems like Windows or macOS. The command line interface approach might be intimidating if you’re not used to working in Linux environments. It’s undeniably tailored for a technical audience, and the learning curve can be steep if you’re unfamiliar with Linux-based systems.
And while the enterprise-level support is fantastic, the licensing cost can be prohibitive for smaller teams or individual users.
“RHEL is the best Linux OS environment anybody can use in their enterprise environments. Mostly because of the support and the security they provide, it frequently provides patches for all the identified bugs. It can be used to deploy, test, and modify any kind of Linux-based package easily. You can deploy this OS using very low hardware resources, and if you are a CLI lover, this is the product you need to choose.”
- RHEL Review, Dulana R.
“I dislike the steep learning curve, the lack of commercial support, and the finicky nature of the older, less mature versions. Centralized management is not really fleshed out, even though things like WebVirtMgr can be configured. Maintenance can be tricky. Migration from one host to another isn't very straightforward either.”
- RHEL Review, Evan L.

Users appreciated that it wasn’t limited to basic voice commands; instead, it supported tasks like file searches, calendar event creation, and quick access to directions during multitasking. According to feedback, Siri felt like a natural extension of the user experience rather than an extra layer to navigate.
Optimized storage in macOS Sierra stands out as a feature designed for content-heavy professionals. According to user reviews, when disk space runs low, the system automatically moves older, less-used files to iCloud, while keeping frequently accessed files local. While some users mention a desire for more control over what gets offloaded, many say the feature significantly reduces storage anxiety.
Auto-unlock with the Apple Watch is another small but impactful addition. Reviewers note that skipping the password prompt and jumping straight into work improves day-to-day productivity—especially when repeated multiple times throughout the day.
However, Sierra isn’t without its limitations. Universal Clipboard, which promises seamless copy-paste across Apple devices, works inconsistently according to user feedback—delivering smooth transitions about 70% of the time but occasionally disrupting workflow with syncing delays.
iCloud integration also receives mixed reactions. While it improves accessibility and syncs data effortlessly, some users report being nudged into storage plan upgrades sooner than expected. The convenience is there, but it comes with a cost.
“The OS is now lighter than before, faster, and has exciting features like a more innovative spotlight search (like a Google search engine). The window management has also improved, with wider support of file systems to mount on the OS.”
- macOS Sierra Review, Jwalin T.
“As a client, macOS Sierra offers an extraordinary arrangement that may be valuable with its predictable mix, solace, further development of components, and by and large quality. While it's an astonishing working structure, there are reliable locales for improvement. Regardless, focusing on the positive points, Sierra's resources overshadow any minor disservices.”
