Juno Tab 4: Two Linux Tablet Models Announced with Core i3 and Core Ultra

Linux PC vendor Juno Computers has announced the “Juno Tab 4,” its 2026 model tablet. The company sells notebooks, mini PCs, and tablets pre-installed with Debian or Ubuntu, and claims this fourth-generation model is its biggest update yet. According to a report by Liliputing, the lineup consists of two models: a 10.5-inch LTE-capable model and a 13-inch Wi-Fi-only model.

Two Variants

The 10.5-inch LTE model is powered by an Intel Core i3-N300 (Alder Lake-N, 8 E-cores/8 threads, up to 3.8GHz, 7W TDP). It features a 1920×1280 display with 500 nits brightness, 12GB of LPDDR5-4800 memory, and a 1TB M.2 2242 SATA III SSD.

The 13-inch model, on the other hand, adopts an Intel Core Ultra 5 115U (Meteor Lake, 2 P-cores + 4 E-cores + 2 LPE cores, up to 4.2GHz, 15W TDP). Its display offers a higher resolution of 2560×1600, also at 500 nits brightness. It comes with 16GB of LPDDR5-5600 memory and a 1TB M.2 2280 PCIe 3.0 x4 NVMe SSD.

Both models support 10-point multi-touch, and while they have different aspect ratios, they share the same 500-nit brightness. The 10.5-inch model weighs 590 grams, and the 13-inch model weighs 850 grams, reflecting a design focused on mobile use.

Features of the 10.5-Inch Model

The standout feature of the 10.5-inch LTE model is its Qualcomm Quectel EG25-G LTE Cat 4 module, enabling mobile communication. In addition to a SIM card slot, this model supports making and receiving phone calls and sending/receiving SMS, functioning like a “large smartphone.”

Its thermal design is passive (fanless), offering silent operation with no fan noise. The battery capacity is 29.6Wh, with support for 36W USB Type-C charging.

The Core i3-N300 has been upgraded from the previous generation’s N100 (4 cores) to 8 cores, significantly improving multi-threaded performance. The GPU is Intel UHD Graphics (up to 1.25GHz, 32 execution units), adequate for typical office tasks and web browsing.

Features of the 13-Inch Model

The 13-inch model is Juno Computers’ first tablet to feature an Intel Core Ultra processor. The Core Ultra 5 115U is an entry-level Meteor Lake chip, but its integrated graphics (up to 1.8GHz, 3 Xe cores) are substantially stronger than the previous generation’s UHD Graphics, potentially capable of handling light PC gaming.

However, the 13-inch model uses active cooling (two fans), in contrast to the fanless 10.5-inch model. The chassis is made of magnesium-aluminum alloy, and at 10mm thick, it is somewhat thicker than typical mobile devices, likely due to a focus on durability.

The battery is a larger 42.71Wh, supporting 65W fast charging. Ports include two USB 3.1 Type-C (data, charging, video output) and one USB 3.0 Type-A, ensuring connectivity with external devices. The presence of a USB Type-A port, absent in the 10.5-inch model, is a distinguishing feature aimed at desktop replacement use cases.

Comparison with the Previous Generation

The previous generation Juno Tab 3 featured a 12.1-inch display and an Intel N100 (4 cores). For the fourth generation, the 10.5-inch model doubles the core count, while the 13-inch model migrates the architecture to Meteor Lake. Performance improvements are significant.

Storage has also evolved from SATA to NVMe (on the 13-inch model), and memory bandwidth has increased to LPDDR5-5600. Display resolution has been increased from the Tab 3, with the 13-inch model’s 2560×1600 panel offering a practical resolution for photo editing and document creation.

Positioning in the Linux Tablet Market

The Linux tablet market is extremely niche compared to Windows, iPadOS, and Android. Apart from specialized vendors like Juno Computers, only limited options such as PineTab and StarLite exist. Many barriers remain for Linux tablets, including device driver support, a lack of touch-optimized applications, and power management challenges.

However, the Juno Tab 4’s adoption of the Intel x86 architecture allows it to run existing Linux desktop applications directly—a key strength. For developers and system administrators, the ability to carry a genuine Linux environment in a tablet form factor holds significant value.

Pricing has not been announced yet, but based on Juno Computers’ past product pricing (around $500–$1,000), the 10.5-inch model may be set at a relatively affordable price. The company has already shipped hardware to reviewers, and a hands-on video has been published on the YouTube channel “Linux Stuff.”

Notably, 2026 is also a period when Intel is expanding its mobile processor lineup. The recently reported news about Intel adding a GPU-less version of Core 200H for small PCs indicates an accelerated strategy for power-efficient, compact devices.

Meanwhile, as the overall Linux ecosystem sees the advancement of closed platforms—such as the move toward Apple Intelligence fully launching with iOS 27 and a renewed Siri AI—the significance of open Linux tablets may be reevaluated. Additionally, the expansion of the smart home market, exemplified by SwitchBot’s parent company acquiring Nanoleaf for roughly 4 billion yen, could lead to scenarios where Linux devices serve as control hubs.

Editorial Opinion

In the short term, the Juno Tab 4 expands the options in the Linux tablet market. The phone functionality of the 10.5-inch LTE model is a differentiating feature not found in existing Linux tablets, potentially appealing to specific user groups (e.g., field workers at telecommunications companies, security-conscious mobile workers).

From a long-term perspective, the widespread adoption of x86 Linux tablets depends on the richness of the application ecosystem. The maturity of touch-optimized GNOME and KDE Plasma Mobile, along with app delivery via Flathub, will be key. Small-scale vendors like Juno Computers are likely to continue driving the market for the foreseeable future.

From the editorial team’s viewpoint, the actual performance and battery life of the Core Ultra 5 115U in the 13-inch model are of primary interest. While Meteor Lake mobile chips have optimized idle power consumption, the need for active cooling affects the tablet user experience. Once pricing is announced, we aim to provide a comprehensive evaluation through a hands-on review.
