A Lenovo lançou sua resposta ao Surface Pro 4 com o IdeaPad Miix 720, principalmente porque o formato 3: 2 é igual e a alta resolução (2736x1.824 do Surface, 2880x1920 do Miix 720) são quase intercambiáveis. Em termos de tela. não há nada a criticar, exceto pelo espaço de cores talvez, mas isso seria demasiado mesquinho.
A vantagem do Miix é que está equipado com muitas portas: 2 USB 3.0 Type-A, USB Type-C Gen2 com Thunderbolt 3 e uma câmera IV para o Windows Hello. No lado técnico, um processador Kaby Lake está instalado, além de um enorme SSD RAID, que é muito veloz.
Infelizmente, o miix 720 não consegue utilizar o poder do SoC plenamente, 10% está faltando durante a carga contínua de aplicativos do dia a dia. Isto o coloca no mesmo nível do Surface Pro 4 i7. Inclusive de modelos muito mais acessíveis, como o Aspire Switch Alpha 12 (i5) se espera que seus SoCs Skylake sejam mais velozes ou pelo menos estejam no mesmo nível.
O Switch Alpha 12 com i5 já está disponível a partir de 750 Euros (~$815), o Microsoft Surface Pro 4 + Type Cover (i5-6300U) a partir de 1200 Euros (~$1304). A questão é esta: Por que comprar o Miix 720 quando o desempenho do processador fica atrás das expectativas?
O Miix 720 certamente não é barato: A versão 7500U, 16 GB e SSD de 1TB custa 1700 Euros ($1845). Para a maioria dos usuários com preferências móveis, no entanto, uma versão pequena com 256 ou 128 GB e Core i3 ou i5 7200U também deve bastar. Estes estão disponíveis a partir de 1070 Euros (~$1162).
A variante menor é suficiente para desfrutar das vantagens do docking, do Thunderbolt 3, da duração da bateria, da ótima tela, da câmera IV com Windows Hello e do versátil teclado (iluminado). Em breve o preço cairá, com 900 Euros (~$978) pela versão pequena i3 sendo uma oferta competitiva.

Contra
Lenovo has launched its response to the Surface Pro 4 with the IdeaPad Miix 720, mainly because the 3: 2 aspect ratio is identical and the high resolution (2736x1.824 of the surface, 2880x1920 of the Miix 720) are almost interchangeable. In terms of the display there is nothing to criticize, except for the color space coverage perhaps, but this would be a bit too stingy.
The advantage of the Miix is that it is equipped with so many ports: 2x large USB 3.0 Type-A, USB Type-C Gen2 with Thunderbolt 3 and then an IR camera for Windows Hello. On the technical side, a Kaby Lake processor is installed, plus a huge RAID-SSD, which is very fast-paced.
Unfortunately, the mix 720 cannot fully utilize the power of the SoC, 10% is missing during continuous load of everyday applications. This puts it at the same level as the Surface Pro 4 i7. Even significantly more affordable models such as the Aspire Switch Alpha 12 (i5) expect their Skylake SoCs to be faster or just on par.
The Switch Alpha 12 with i5 is already available from 750 Euros (~$815), the Microsoft Surface Pro 4 + Type Cover (i5-6300U) from 1200 Euros (~$1304). Here is the question: Why buy the Miix 720 when processor performance falls short of expectations?
The Miix 720 is certainly not cheap: The 7500U, 16 GB and 1 TB SSD version costs 1700 Euros ($1845). For most users with mobile preferences, however, a small version with 256 or 128 GB and Core i3 or i5 7200U should also suffice. These are available from 1070 Euros (~$1162).
The smaller variant is enough to enjoy the docking advantages of Thunderbolt 3, the runtime, the great display, the IR camera with Windows Hello and the versatile keyboard (illuminated). Sometime soon the price will fall, with 900 Euros (~$978) for the small i3 version being a competitive offer.
