This review really lacks context, as it primarily reviews the two devices on a pure tablet basis (with a brief nod to Windows 10 Home). Because of an insurmountable lead in the pure tablet app universe, the iPad comes in strong as just a tablet. However, if you are looking for a productivity device, the Surface Go 2 wins hands down. Even with PadOS 13.5 trackpad support, the keyboard, mouse, and most importantly file management is a shadow of what Windows provides. Add to this that SG2 is great at iTunes (videos), Netflix, Disney Plus, Prime Video, and YouTube, and you have a good overall experience. It lacks as a reading and gaming device, but then even Samsung has made little inroad into pure Android tablet space against iPad.
If you want a pure tablet experience, stay in the walled garden. If you need more, SG2 is much better than a tie with iPad.
