Breve Análise do Conversível Lenovo Yoga Book C930 (i5-7Y54, LTE, E-Ink)

Christian Hintze, 👁 Sebastian Jentsch (traduzido por Ricardo Soto), 12/28/2018

3-in-1 convertible. O novo Yoga Book tem uma tela E-Ink em vez de um teclado e pode ser considerado uma combinação de um portátil, um tablet e um e-reader. Além disso, você também pode digitalizar textos e desenhos com este multifuncional. O dispositivo é baseado em seu antecessor a partir de 2016, mas oferece muitas mudanças e melhorias. Por exemplo, fornece melhor desempenho. Por outro lado, também deixou de lado pelo menos um recurso. Será que o Yoga Book 2018 vale o dobro do preço da versão antiga? Descubra em nossa análise.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
27 ms ... rise ↗ and fall ↘ combined↗ 13 ms rise
↘ 14 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.5 ms).
       Response Time 50% Grey to 80% Grey
43 ms ... rise ↗ and fall ↘ combined↗ 23 ms rise
↘ 20 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 59 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9891 (minimum: 43 - maximum: 142900) Hz was measured.

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.
