6. Conclusion
The Google Cr-48 and MobLab Wyvern represent two different stages of the educational technology lifecycle.
The Wyvern MobLab is the sovereign device. It runs a hardened fork of postmarketOS (Alpine Linux) with a custom kernel that disables all peripheral DMA. It comes pre-loaded with moblabd, a daemon that allows phones to form a local, encrypted mesh network without any internet backbone. The device’s killer feature is "Offline-First P2P." Two MobLabs can share 100MB files at 300 meters via LoRa radio (sub-GHz) while the user’s cellular modem is physically disconnected. Where the CR-48 required a server, the MobLab requires only another MobLab.
- Processor: The MobLab has a slightly more powerful processor in the Intel Atom N550, which provides a 10% boost in performance compared to the CR-48's N455 processor.
- Storage: The MobLab offers more storage space with a 30GB SSD, compared to the CR-48's 16GB SSD.
- Ports: The MobLab has a more comprehensive set of ports, including an additional USB port and an SD card slot.
- Battery Life: The MobLab claims to offer up to 8 hours of battery life, while the CR-48 is rated for around 6-7 hours.
