Contra
O novo e redesenhado Yoga 920 é o melhor Yoga da série 900 até agora e está longe de ser apenas uma atualização de hardware simples. O desempenho certamente está à altura da nova CPU quad-core e o SSD NVMe incrivelmente veloz, mas a Lenovo também melhorou outras áreas: o novo conversível agora possui 2 portas Thunderbolt 3, uma localização melhorada da webcam, um teclado modificado, suporta uma caneta ativa para pela primeira vez, e funciona durante mais tempo mais tempo com uma carga. A Lenovo, obviamente, levou em consideração o feedback dos clientes, o qual é agradável de se ver.
O chassi de alumínio é bonito e bastante robusto e o design watchband da dobradiça ainda atrai olhares. A tela poderia ser um pouco mais clara, e a relação de contraste e a precisão da escala de cinzas também poderiam ser melhores. Há também uma questão de tamanho: o Yoga ainda é um dos maiores conversíveis, o que não o torna fácil de segurar no modo tablet. Mesmo assim, alguns usuários podem apreciar a tela extra. A falta de um "Lift'n Lock" ao estilo ThinkPad Yoga também deixa as teclas expostas, então é necessário ter mais cuidado para evitar danos. O afogamento sob carga pesada reduz um pouco o enorme potencial de desempenho dos núcleos extras da CPU, mas o desempenho geral ainda está em alta, então não consideramos essa como uma grande desvantagem. Uma vantagem adicional: o irritante som de assobio que encontramos durante a nossa análise do antecessor, o Yoga 910, definitivamente não é mais um problema.
O Yoga 920 é um 2-em-1 atraente, muito bem projetado. Os usuários que considerem um conversível de 13,3 polegadas como o HP Spectre x360 ou o Dell XPS 13 definitivamente devem dar uma olhada no Yoga um pouco maior.
