El Latitude E5440 ofrece muchas características deseadas por los trabajadores: sólida construcción, agradables dispositivos de entrada, brillante pantalla HD+, bajas emisiones, buen rendimiento, y larga duración de batería debido al procesador ULV. Apenas hay de qué quejarse porque el Latitude hace todo lo que se supone que debe hacer por lo que cuesta. Los perfeccionistas querrán una pantalla IPS de gran contraste, pero ni el premium Latitude E6540 lo llevaba (FHD TN). Nuestro modelo E5440 también podría haber tenido una mejor webcam para posibilitar videollamadas de mayor resolución o fotos usables.
El cliente puede preferir un LifeBook que está en el mismo segmento de precios que nuestro modelo de pruebas (750 - 950 Euros). También trae un HD+, pero además tiene DisplayPort. El HP ProBook 640 G1 sería interesante para los fans del HD+ que no quieran vivir sin la potencia de una CPU de voltaje estándar. El Lenovo ThinkPad L440 tiene excelentes dispositivos de entrada, un robusto chasis y un HD+ (modelo a la venta). Por último, los tres contendientes son virtualmente iguales en términos de calidad y precio, aunque Lenovo es el que tiene el precio más bajo (L440 HD+ a partir de 750 Euros). Así, detalles como el DisplayPort (HP, Fujitsu) o un modem 3G ready (E5440) serán el factor decisivo.
