7.2/10verdict: buy

The Raspberry Pi 400 is for anyone who wants a complete, compact Raspberry Pi desktop with the keyboard built in and no assembly. It suits learners, classrooms and homelabbers who want a small terminal or light desktop machine running Raspberry Pi OS. It is a weaker fit for anyone who needs easy GPIO access or fast internal storage.

Raspberry Pi Zero WH

5.9/10verdict: good, not the best

The Raspberry Pi Zero WH is for people who want a small, low-power board with GPIO ready to use straight away. It suits single-purpose projects that need Wi-Fi, Bluetooth and header-based add-ons rather than much processing power. It is not aimed at anyone who needs wired networking, fast storage or several services running at once.

Strengths and weaknesses

Raspberry Pi 400

  • + Keyboard and computer in one compact case
  • + Raspberry Pi OS preinstalled on the SD card
  • + Gigabit Ethernet and two USB 3.0 ports
  • − microSD only, with no M.2 or eMMC
  • − GPIO access is awkward and needs an adapter
  • − Keyboard feels cheap and spongy to some owners

Skip it if:

  • Buyers who want M.2, SSD or eMMC storage on the board.
  • Makers who will use the GPIO header often and want easy access.
  • Anyone who wants a separate bare board to mount in their own case.

Raspberry Pi Zero WH

  • + 40-pin GPIO header comes pre-soldered
  • + Same header as flagship Model B boards, so HATs fit
  • + Wi-Fi and Bluetooth built in
  • − Single-core 32-bit CPU with 512 MB RAM
  • − No wired Ethernet; 2.4 GHz Wi-Fi only
  • − microSD is the only storage option

Skip it if:

  • Buyers who need wired Ethernet or 5 GHz Wi-Fi
  • Anyone running several containers or VMs on one board
  • Users who want storage beyond a microSD card
