    Detailed Test Results

    Performance: Performance was only fair. Speed was slow but adequate for productivity and Web-based tasks such as word processing, Web browsing, and online game play.

    Portability: This Chromebook is a Very Good choice for traveling. Battery life lasted 11.75 hours in a light load of web browsing tests, and 6.75 hours in a heavier load of 4K video playback tests. Results could get you through a typical workday, under a workload of mixed use. At 4.4 lbs, weight was typical for a Chromebook this size and light enough to carry.

    Ergonomics: Some features of the keyboard and case were well-designed, making it comfortable or convenient to use. The keyboard has large keys and was comfortably sized. Its high contrast letters were easy to read. The power button labeling was hard to read when the laptop is off, and it was inconveniently placed, either difficult to reach or too easy to accidentally press. Friction on the touchscreen may prevent fast swiping, and fingerprints may take some effort to clean off. Testers liked the sturdy build of the chassis.

    Display: The display quality was Very Good overall. Colors were in the ballpark, though not completely accurate. The display has a wide viewing angle, especially important if more than one person needs to see the screen at a time, say, for a video or presentation.

    Useful features and attributes on this model include: The Chromebook has a convertible form factor and can be folded backwards for use as a tablet. You can connect common external devices such as hard drives and DVD players using USB 3.1 Gen 1 (5 Gbps) for maximum performance. The power supply adds a lightweight 0.6 lbs, not too much more than the laptop weight.

    Downsides: No significant negative features.
