In this review, I cover the One-Netbook One Mix 4 10.1-inch model, which is also known simply as the One-Netbook 4 or the 4 Platinum in its higher-end configurations. This device is a compact 360-degree convertible laptop powered by Intel 11th generation Tiger Lake U series low-power processors. The 10.1-inch form factor stands out as somewhat unusual in today’s market, yet it strikes an excellent balance for portability.

One-Netbook has built a reputation for creating highly miniaturized laptops, including even smaller models around seven or eight inches. Unlike the cheap plasticky netbooks from the late 2000s, this machine feels thoroughly modern and premium. It features a CNC-machined 6000 series aluminum chassis paired with a sharp QHD IPS display that supports both touch input and active pen use. This is a true premium device that has simply been scaled down for maximum portability rather than compromised on quality.

The One Mix 4 weighs just 769 grams, or roughly 1.7 pounds, making it exceptionally light and slim enough to slip into a bag without hesitation. It delivers a more authentic laptop experience compared to the company’s tinier models, where screen real estate becomes too limiting for comfortable work. This size feels ideal for users who want a capable machine they can carry on a whim without committing to the weight of a full-sized laptop.

Display

The screen uses a QHD+ resolution in a 16: 10 aspect ratio, which provides ample vertical space for productivity tasks. Out of the box, Windows applies 250 percent scaling, which can cause some dialog boxes and elements to run off-screen, so adjusting it down to around 200 percent delivers much better usability while keeping everything sharp and readable.

Image quality is impressive for such a compact device. The panel offers good brightness, solid contrast, and near full sRGB coverage, resulting in vibrant and pleasant visuals. It appears even brighter in real-world use than the measured numbers suggest. The glossy touchscreen finish works beautifully at this size, enhancing the overall experience for note-taking, ebook reading, or viewing comics. Calibration shows a slight excess of blue tint out of the box, but this can be easily corrected through Windows settings or a colorimeter for more accurate colors.

Performance and Thermals

Hardware performance impresses given the miniature chassis. The available configurations include Intel Core i5 and Core i7 processors with Iris Xe graphics, the same chips found in premium ultrabooks like the Lenovo ThinkPad X1 Nano and X1 Titanium Yoga. This makes the One Mix 4 perfectly capable of serving as a daily driver for most users who do not require heavy workstation-level power.

A cooling fan is included, and it matches the size typically seen in 13-inch ultrabooks. Under load, the fan spins up noticeably but remains relatively quiet. Sustained heavy tasks such as long video exports will cause some thermal throttling, but overall behavior stays consistent with other compact premium laptops in this class. The device handles everyday productivity, browsing, and lighter creative work with ease.

Pricing starts around one thousand dollars for the base Core i5 model with eight gigabytes of RAM and a 256 gigabyte M.2 NVMe SSD. The higher-end Platinum version, equipped with a Core i7, 16 gigabytes of dual-channel RAM, and a 512 gigabyte SSD, commands approximately fifteen hundred dollars. While these figures position the One Mix 4 as a luxury item, especially as a secondary device, it demonstrates that small laptops no longer need to feel underpowered or cheaply made.

Keyboard and Trackpad

The keyboard on a 10.1-inch device requires some adjustment but performs better than expected. Key travel feels decent with firm tactile feedback that many users will appreciate after a short adaptation period. The keys demand a full deliberate press, which initially led to some missed strokes until muscle memory adjusted. Backlighting is available in white and can be toggled with a simple function key combination.

The Microsoft Precision trackpad is on the smaller side, which affects multi-finger gestures. Two-finger scrolling works reliably only when fingers stay perfectly parallel; otherwise detection can falter. Still, it remains functional for a device of this size, and most users will adapt quickly.

Connectivity

Port selection includes two USB Type C ports on the left side with one supporting high speed 40 gigabits per second transfers and even external GPU connectivity. A USB 3.0 port sits on the right alongside a headphone jack and microSD card reader. Given the compact design, some dongle use for USB-A peripherals becomes necessary, but this is an acceptable trade-off.

Audio and Webcam

Audio output comes from a single mono speaker, which is understandably limited due to the small chassis. Sound quality is basic and lacks the depth, volume, and stereo separation found on larger laptops, making it suitable mainly for casual listening or system notifications rather than music or movies. The built-in microphone performs adequately for voice calls and video conferencing when paired with an external solution.

Notably, the One Mix 4 does not include a built-in webcam. Users who need video calling capabilities will have to rely on an external USB webcam accessory. This omission keeps the design slim and focused but represents a minor compromise for a device aimed at portability and productivity.

Battery Life

A 38.5-watt-hour battery powers the system, paired with a compact 45-watt charger that is barely larger than many phone adapters. In mixed productivity testing involving office work, video streaming, and light photo editing at around 200 nits brightness, the device delivered approximately six hours of runtime. With further optimizations such as lower brightness and balanced power settings, users can realistically reach seven hours or slightly more. This is respectable for the size, though not class-leading.

Build Quality and Upgradability

The dark blue aluminum finish looks elegant but shows fingerprints readily. Opening the bottom panel is straightforward using small Phillips screws, after which the internals reveal themselves easily. The cooling setup includes a standard ultrabook-sized fan and heat pipes. Users can upgrade the M.2 SSD while the RAM and Wi Fi card remain soldered. Battery replacement is also possible for those comfortable with basic disassembly.

Final Thoughts

The One-Netbook One Mix 4 represents a fascinating and well-executed miniature laptop. It proves that compact devices can deliver premium build quality, strong performance, and excellent portability without major sacrifices. While the 10.1-inch screen prevents it from replacing a full-sized primary machine for most people, it excels as a highly capable secondary device or an everyday carry option for those who value lightness and versatility.

Whether for note-taking, media consumption, or productive work on the go, this convertible stands out as a thoughtfully designed product. Its premium pricing reflects the engineering involved, but for enthusiasts who appreciate clever miniaturization, it is a device that many will simply want to own. Availability continues to expand through various retailers and import channels, making it accessible to those intrigued by this unique form factor.
