Pro
Contra
O novo Yoga Book possui uma tela E-Ink que o torna muito singular. Sua maior vantagem é sua versatilidade. É extremamente pequeno e leve e pode ser usado para desenhar, como um portátil ou tablet ou como um e-reader. Mas é claro que essa flexibilidade também requer alguns compromissos.
Por exemplo, o teclado não é adequado para digitadores frequentes e não tem iluminação de fundo. A escassa seleção de portas também pode ser incômoda para usuários de portáteis tradicionais. Se um e-reader é tudo o que você precisa, provavelmente encontrará dispositivos ainda mais leves.
O Livro da Lenovo é dirigido a pessoas que gostariam de combinar todas as suas funções (táctil, caneta, e-reader, etc.) em um único dispositivo. Os usuários que estão procurando um portátil normal, podem ficar mais felizes com um dispositivo diferente.
No entanto, é surpreendente ver como a Lenovo conseguiu combinar todas essas funções em um dispositivo tão leve. Seu design e funções geniais (knocking) transformam o Book C930 em uma verdadeira atração. Como não temos uma categoria separada para as telas E-Ink em nosso sistema de avaliação, adicionamos manualmente dois pontos ao resultado.
Alguns usuários podem considerar o preço como mais uma desvantagem. Com um preço inicial de $1050, o dispositivo custa cerca de duas vezes mais do que seu antecessor. Além das muitas melhorias, algumas funções também desapareceram. A possibilidade de digitalizar imagens do papel não está mais disponível. A melhor câmera principal também está faltando e, infelizmente, a duração da bateria é significativamente menor que o de seu predecessor. Em vez disso, o desempenho aumentou drasticamente e a tela também é melhor. Por último mas não menos importante: Atualmente, o dispositivo não tem concorrentes reais.
