O Lenovo IdeaPad Duet é um pequeno conversível que roda Chrome OS. Graças ao suporte de Android e Linux, existem inúmeras possibilidades de aplicação para o pequeno tablet. Mas lembre-se de que o Android e o Linux só funcionam virtualmente no dispositivo; consequentemente, você tem que viver com velocidades reduzidas.
Até mesmo o navegador Chrome nativo faz o SoC MediaTek suar, e você tem que conviver com um leve engasgo.
Mas, em troca, você obtém um navegador de desktop completo e, em combinação com o Linux, uma solução móvel interessante para desenvolvedores da web. Mas se você deseja apenas usar aplicativos Android e não precisa de um navegador para desktop, um tablet Android ou um iPad é provavelmente a melhor escolha para você.
As medidas técnicas do IdeaPad não atrapalham. A tela mostra boas características - especialmente para a faixa de preço. Os usuários provavelmente desejarão um brilho ainda maior para uso externo à luz do sol. O teclado e touchpad são adequados para o tamanho e faixa de preço - mas os digitadores frequentes deveriam recorrer a dispositivos maiores aqui. Além disso, não há nada do que reclamar em termos de duração da bateria e emissões. Como resultado, a combinação de Linux, Android, um navegador Chrome completo, bateria de longa duração e mobilidade pode ser um compromisso interessante para alguns usuários.
