Every laptop in your office is probably running Windows or macOS. Your email is almost certainly on Microsoft 365 or Google Workspace. Your files live in OneDrive, SharePoint, or Google Drive. And every single byte of that data sits under US legal jurisdiction, whether you are in London, Nairobi, or Kabul.
The CLOUD Act of 2018 allows US law enforcement to compel American tech companies to hand over data stored anywhere in the world, on any server, in any country. No UK court order required. No notification to the data subject.
I work in international development. The data my organisation handles includes programme financials, personnel records, partner organisation details, and sensitive beneficiary information across more than 80 countries. The idea that all of it sits one CLOUD Act request away from a US federal agency is not a risk I am comfortable ignoring.
So when Star Labs Systems, a quietly impressive Sheffield-based hardware company, released the StarBook Horizon, I bought one. A Linux-native laptop with open-source firmware, no Intel Management Engine, a hardware wireless kill switch, and zero dependency on any US cloud platform.
The Hardware: What It Is Actually Like to Use
The lid does not bow. Nothing creaks or groans as you use it. The hinge is firm without seeming stiff. The hand feel is excellent throughout. It feels as if it was made by people who understand that laptops get knocked about, but still need to look good and be perfectly usable.
The screen took me a day or two to properly appreciate. The 3:2 aspect ratio gives you more vertical space, which sounds minor until you spend a day in it and then go back to a 16:9 panel and feel like you are reading through a letterbox.
The keyboard is good. Key travel is enough that you know you have pressed something, the action is consistent across the board, and I wrote several thousand words on it without any of the hand fatigue I get from shallow chiclet keyboards on some thin-and-light machines.
Battery life: In actual all-day use, I got around 7 hours. Enough for a full working day in an office. The 65W USB-C charging is fast enough that topping up from a meeting room socket for twenty minutes buys you a couple of hours.
The Firmware: Where It Gets Interesting
Most laptops ship with a proprietary UEFI that you cannot read, audit, or meaningfully configure. The Horizon runs coreboot, which is fully open source, and the entire build for this machine is published on Star Labs' GitHub.
The security options are not marketing hype: TPM 2.0, Measured Boot with PCR extension at each boot stage, Total Memory Encryption, and BIOS lock. Measured Boot means a cryptographic record is built of everything that ran during startup. If something in that chain has been tampered with, the PCR values change, and you know about it.
The wireless kill switch is a real switch. It cuts the RF-kill lines to the wireless module directly. The OS can see that the radios are off, but it cannot turn them back on through software.
Zorin OS: Linux That Does Not Make You Feel Like You Are Being Punished
Zorin is an Irish Linux distribution built on Ubuntu 22.04 LTS. The LTS base matters: it means a five-year support window, stable package repositories, and a well-understood security update cadence.
The layout options include a Windows 11-style taskbar, a macOS-style dock, and a classic desktop. You pick the one that corresponds to where your users are coming from. Staff who are anxious about change calm down noticeably when they sit in front of it and discover that their muscle memory still applies.
Snap packages are deliberately excluded from Zorin, which is the right call: Snap's mandatory connection to Canonical's proprietary Snap Store is precisely the kind of soft dependency on a US-adjacent infrastructure that defeats the point of this exercise.
So Who Should Actually Buy This?
If you work in international development, humanitarian response, civil society, or any sector where you handle sensitive data in environments with active state surveillance, the question you should be asking is not whether Linux is inconvenient. It is whether the convenience of Windows is worth the jurisdictional risk.
I would suggest it is not.
And for individual professionals who are paying attention to what is happening with US tech policy, who have looked at the CLOUD Act and FISA 702 and thought "this is not fine actually," the Horizon with Zorin Pro and Proton Suite is a complete, working, professional answer.
It runs all day. It looks great in a meeting. It does not phone home. What more do you want?
Should this be used in the field or in the office in the international aid sector? Absolutely yes. In the office, it is a capable, professional machine that handles every standard productivity task cleanly. In the field, it has the added advantage of hardware-level privacy controls, a sovereign software stack, and a repairability story that matters when you are not close to an authorised service centre.
