The unit reviewed is the top configuration with 16GB DDR5, priced at $799.99. A notable discovery: TOS installs on user-inserted disks rather than onboard storage, making drive migration between devices seamless. TOS 7 brings a cleaner UI and better storage management, but the 'AI-native' marketing claim is questioned — the OpenClaw AI feature is merely an orchestration layer requiring external LLM configuration, not on-device inference. Several software rough edges are noted: global search limited to home directory, Jellyfin subdirectory browsing issues, no keyboard navigation in Photos, and apps needing manual re-enabling after each reboot. The underlying Linux environment is Ubuntu 22.04, which reaches EOL in April 2027 — a concern for a newly launched device. Hardware performance is solid, with under 20% CPU/RAM load during photo indexing and under 10% during 4K streaming. ## Full article daily.dev links to this article rather than hosting it.
