El Acer Chromebook 13 CB5-311-T0B2 causa una buena impresión en general. El rendimiento de la CPU es más que suficiente para el campo de aplicación de un Chromebook, y está al nivel de los Intel Bay Trail Celerons. El núcleo gráfico tiene un rendimiento sensiblemente superior y puede competir con el Intel HD Graphics 4400. El ordenador funciona en silencio y apenas se calienta. Lo que es más, el Chromebook da buena duración de batería. Durará un día en la universidad o la escuela con una sola carga de batería. No hay que olvidar el decentísimo teclado.
