Contra
O Acer Swift 7 SF714 é um subportátil ultracompacto que é bem adequado para uso móvel. O Swift 7 melhora ligeiramente o seu antecessor em todas as áreas; a maior diferença é a maior tela multi-touch de 14 polegadas. A Acer também revisou o chassi para tornar o novo Swift 7 ainda mais fino do que seu antecessor. Infelizmente, isso compromete a estabilidade.
A Acer manteve a seleção limitada de portas com o seu mais recente Swift 7, mas agradecemos a inclusão de um modem LTE. Desejamos apenas que a Acer tenha incluído um leitor de cartões de memória, pois isso aumentaria a flexibilidade do dispositivo.
Elogiamos muito os acessórios incluídos. A capa tem uma sensação premium e é bem feita. Isso também se aplica ao hub USB Type-C, que expande a seleção de portas do Swift 7 para uma porta USB tipo A e uma única porta HDMI.
O Acer Swift 7 SF714 melhora o seu antecessor em todas as áreas, particularmente com sua tela multi-touch maior. O preço também mudou, ou seja, subiu. No entanto, a Acer esqueceu um truque a este respeito?
Uma grande crítica ao Swift 7 é seu preço. O Acer Swift 7 SF714 custa uns impressionantes 1.699 Euros (~$1.973), o que é uma relação de preço-desempenho significativamente mais baixa do que com o seu antecessor. Em última análise, os potenciais compradores devem decidir por si mesmos se as inovações e o desempenho levemente aumentado justificam esse aumento acentuado no preço.
Não podemos dar ao Acer Swift 7 SF714 uma recomendação de compra clara apenas devido ao seu elevado preço avulso.
Outra queixa menor que temos é com o touchpad. A ausência de um mecanismo de clique torna o uso do dispositivo muito mais difícil no uso diário.
No geral, o Acer Swift 7 SF714 é um dispositivo inteligente e ultra móvel com uma duração de bateria impressionante que é manchado pelo seu preço elevado.
