Today, Chromebooks own 60% of the US K-12 education market. That statistic exists because the CR-48 walked so others could run.
Simultaneously, a company called Wyvern (later absorbed into the mobile device management ecosystem) released the . If the CR-48 was a hippie commune, the MobLab was a prison warden.
The MobLab was a portable charging and syncing cart—essentially a ruggedized suitcase on wheels. Inside, it held 20 to 30 iPads or Android tablets. Its "smarts" came from a built-in Linux motherboard that managed USB connections. It could flash firmware, sync apps, and bulk-update devices in a school closet without Wi-Fi.
, this isn't a laptop you type on. It is a "Mobile Laboratory"—a self-contained automated testing environment used by hardware partners to qualify their own ChromeOS devices. How to run fwupd tests with Moblab — LVFS documentation google cr-48 vs wyvern moblab
Both the and the Wyvern MobLab represent mobile, purpose-built hardware designed for testing and development outside a traditional office. However, they come from vastly different eras and objectives. The CR-48 was a 2010 pilot laptop for cloud-native Chrome OS , while the MobLab is a modern, ruggedized portable network emulation and testing appliance used by security researchers and network engineers.

But the CR-48 won the philosophical war. It proved that a cloud-centric, secure, low-power, virus-proof laptop was viable. The lessons from the CR-48 directly led to the (the first retail Chromebook) and, eventually, the Pixelbook and modern ChromeOS. Today, Chromebooks own 60% of the US K-12 education market
Here’s a proper technical write-up comparing the (a historic pilot device) and the Wyvern Moblaboratory (MobLab) (a modern portable network testing platform). The comparison focuses on purpose, hardware philosophy, software, and legacy.
The Cr-48 features an 11.6-inch display, a 1.66 GHz Intel Atom processor, 2GB of RAM, and a 16GB SSD. It also comes with a range of ports, including USB, HDMI, and an SD card slot. The device runs on Chrome OS, which provides a seamless web-based computing experience.
While the and Wyvern MobLab both originate from the world of ChromeOS, they represent two completely different eras and philosophies of Google’s ecosystem. One was a "pilot" laptop designed to prove a concept to the world, while the other is a specialized piece of infrastructure meant to keep that ecosystem running smoothly.

It famously replaced the Caps Lock key with a Search key—a legacy that persists on every Chromebook today.
The hardware differences reflect their distinct roles as a portable laptop versus a stationary test server. MobLab - Chromium
