Contra
Con el IdeaPad Miix 720 Lenovo lanza una respuesta al Surface Pro 4, la similitud de las pantallas con el mismo ratio 3:2 y la alta resolución (2736x1.824 en el surface, 2880x1920 en el Miix 720) hace que sean casi intercambiables. Respecto a la pantalla no hay nada que criticar excepto, quizás, que la cobertura del espacio de color es mejorable.
La ventaja del Miix es que está equipado con más puertos: 2x USB 3.0 Type-A, USB Type-C Gen2 con Thunderbolt 3 y una cámara IR para usar Windows Hello. En el aspecto técnico, se incluye un procesador Kaby Lake además de un RAID-SSD muy rápido.
Desafortunadamente, el mix 720 no puede utilizar toda la potencia del SoC, se pierde un 10% de rendimiento durante el funcionamiento continuo de aplicaciones cotidianas. Esto lo pone al mismo nivel que el el Surface Pro 4 i7. Incluso modelos más asequibles como el Aspire Switch Alpha 12 (i5) llevan su SoC Skylake SoCs a rendimientos iguales o superiores.
El Switch Alpha 12 con i5 está disponible desde 750 Euros, el Microsoft Surface Pro 4 + Type Cover (i5-6300U) por 1200 Euros. La pregunta entonces es: ¿Por que comprar el Miix 720 cuando el rendimiento del procesador está por debajo de lo deseado?
El Miix 720 no resulta barato: La versión con 7500U, 16 GB SSD de 1 TB cuesta 1700 Euros. Para la mayor parte de los usuarios, sin embargo, la versión con 256 o 128 GB y Core i3 o i5 7200U debería ser suficiente. Están disponibles por 1070 Euros.
La variante más pequeña es suficiente para disfrutar de las ventajas del Thunderbolt 3 al funcionar conectado a la base, la duración de batería, la gran pantalla, la cámara IR compatible con Windows Hello y el versátil teclado retroiluminado. En algún momento el precio bajará, un precio de unos 900 euros por la versión i3 sería un precio competitivo.
