Contra
A Lenovo cometeu um erro com o ThinkPad E14 Gen 1: Fez um downgrade da memória para single-channel para um chassi mais fino. O Lenovo ThinkPad E14 Gen 2 corrige este erro. Ao mesmo tempo, oferece melhor desempenho que qualquer E ThinkPad até agora, graças à AMD Ryzen 4000.
Com isso em mente, a série ThinkPad E, claro, continua sendo uma série de portáteis orientada para o orçamento. Isso explica a tela relativamente escura e com cores fracas, a ausência do slot microSD e a pobre seleção de portas. Os ThinkPads das séries L e T têm vantagens aqui, e o mesmo vale para os recursos empresariais disponíveis. Além disso, o ThinkPad E14 Gen 2 aquece em torno do apoio para as mãos sob uso intenso, e os materiais usados aqui tornam o chassi pesado e a duração da bateria poderia ser melhor.
Dispositivos de entrada ThinkPad, AMD Ryzen 4000 e acessível: Se alguém busca essa combinação, o ThinkPad E14 Gen 2 pode ser a escolha ideal para um portátil de escritório doméstico - embora os cortes de custos da Lenovo possam ser um obstáculo para alguns usuários.
Se você está disposto a diminuir suas expectativas para a tela e seleção de portas, o Lenovo ThinkPad E14 Gen 2 ainda pode ser atraente. Os dispositivos de entrada muito bons, chassis compacto e ventilador silencioso são todos atributos desejáveis. O E14 AMD também é bastante atualizável e com o AMD Renoir tem uma ótima relação preço/desempenho. Podemos recomendar o ThinkPad E14 Gen 2 para clientes mais sensíveis ao preço.
