What’s the one thing a child-friendly tablet should have? How about decent parental controls? Sadly, that, and a lot of other things—such as good battery life, audio, and performance—were also missing from the Arnova ChildPad. No kid will want to use a slate with a dim and muddy screen, tinny sound, and less than five hours of endurance. No adult will want a tablet that can’t access Google Play, and whose only parental controls let you block web sites. As a company with lots of experience designing tablets, Archos should have known better.
