Contra
Como seus predecessores e irmãos de 7 e 10 polegadas, o Amazon Fire HD 8 (2017) oferece uma incrível relação preço-desempenho.
Equipado com uma tela IPS de 8 polegadas de 1280x800, um SoC quad-core MediaTek MT8163, e 16 ou 32 GB de armazenamento, o Fire HD oferece suficiente desemepnho ára o uso diário. E, embora isso também seja verdade para seus concorrentes, eles tendem a ser mais caros. Em qualquer lugar entre $80 e $125, você terá um tablet bem feito com longa duração da bateria e som estéreo decente.
Aqueles de vocês, que já possuem o antecessor, podem ignorar esta última versão. Além de alguns aprimoramentos menores (cartão microSD maior, GPU um pouco mais veloz), ele realmente não mudou muito.
Por outro lado, o tablet vem com seu próprio conjunto peculiar de limitações, o foco essencialmente óbvio no ecossistema da Amazon em geral. A Play Store do Google não é oficialmente suportado e sua instalação, anulará sua garantia. O Fire HD 8 (2017) é o aparelho perfeito se planeja ficar dentro do universo da Amazon.
Outras limitações são simplesmente terríveis, como o SO Android 5.1.1 desatualizado, a falta do GPS e WWAN, e as câmeras pobres que você teria que ser quase cego para encontrá-las remotamente aceitáveis.
