O Dell Inspiron 7390 2-em-1 Black Edition de US$ 1.249 (conforme configurado) pode não parecer muito diferente de seu antecessor, mas na verdade resolve algumas das maiores reclamações que tivemos sobre o Inspiron 7386 2-em-1. A principal delas é o consumo de energia no modo ocioso, que caiu quase para a metade, e a duração da bateria, que é 40% mais longa do que antes. Também não detectamos nenhum ruído da bobina em nossa unidade de teste, e a tela é um pouco mais brilhante do que antes. Até o desempenho da CPU também está um pouco melhor do que era anteriormente, apesar do fato de as duas máquinas serem impulsionadas pelo mesmo chip.
Além disso, a tela UHD é atraente, com boa reprodução e calibração de cores prontas para uso, e o botão liga/desliga redesenhado (com leitor de digitais integrado) e o layout do teclado funcionam bem em nossa opinião. O design da construção e da carcaça é bom para sua classe e parece um pouco mais resistente do que alguns dos concorrentes de metal mais finos. Por fim, o novo design inteligente da dobradiça da Dell, que incorpora uma cavidade magnética para a Dell Active Pen incluída, é uma das melhores soluções de armazenamento que vimos para uma caneta de tamanho normal.
O Inspiron 7390 2-em-1 aprimora seu antecessor de várias maneiras - mais notavelmente, duração da bateria muito melhor e desempenho ainda melhor. Apesar de algumas reclamações sobre os dispositivos de entrada e o valor questionável da CPU Core i7, ele representa uma alternativa séria aos concorrentes de fabricantes como Lenovo e HP.
Ainda assim, algumas das mesmas queixas permanecem. O desempenho ainda é insatisfatório no contexto, com os resultados publicados pelos concorrentes do cTDP Up, como Lenovo’s ThinkBook 13s, que são realmente melhores. A seleção de portas é escassa e a falta de Thunderbolt 3 e uma porta Kensington Lock incomodará alguns usuários. O teclado é razoavelmente bom, mas a resposta e a força de atuação poderiam ser melhores. Da mesma forma, os botões do touchpad integrado exigem muita força para serem accionados e se tornam bastante cansativos para operar depois de um tempo. Por fim, embora a tela seja certamente agradável, teria sido bom ter uma opção de FHD, o que aumentaria bastante a duração da bateria.
Alguns concorrentes diretos que vale a pena considerar incluem o ThinkPad X1 Yoga, Breve Análise do Conversível HP Envy x360 13:, Uma alternativa ThinkPad X390 Yoga, e—no lado mais caro—o Latitude 7400 2-in-1. Além das preocupações sobre os dispositivos de entrada e as lamentações que cercam os chips de preço mais alto, o peso do Inspiron 7390 2-em-1 agora parece uma alternativa razoável aos populares conversíveis da série Yoga e x360 que se elevavam acima do seu antecessor.
