Com o L470, a Lenovo oferece um ThinkPad orientado para o orçamento, que, acima de tudo, deve ser interessante para estudantes e empresas.
Por um preço relativamente baixo, o L470 oferece o conhecido e excelente teclado ThinkPad, incluindo o TrackPoint. Também na caixa: Uma tela IPS Full HD, que não pode ser considerada como garantida nesta categoria de preço. A carcaça de plástico não se sente de qualidade alta, no entanto, se sente bastante robusta e possui dobradiças duráveis. Como portátil empresarial, o L470 oferece uma boa variedade de portas. Aqui, é preciso lamentar a falta de uma porta tipo USB tipo C, no entanto, isso é um pouco compensado pelo fato de que a Lenovo ainda integra uma porta docking dedicada. Portanto, não se depende das estações dock USB Tipo C. O que também é bom é que a Lenovo ainda equipa o L470 com uma porta VGA, que é uma característica única entre os ThinkPads atuais. Para escolas, universidades e empresas que ainda utilizam projetores antigos, este é um importante ponto de venda. Neste caso, a boa duração da bateria e a flexibilidade de uma bateria substituível devem ser apreciadas, embora ela eleve um pouco o aparelho.
A Lenovo não cometeu grandes erros. Em primeiro lugar e acima de tudo nesta categoria está o irritante ruído da bobina, o que é uma grande pena, pois, de outra forma, o dispositivo teria sido completamente silencioso durante a o modo inativo. O afogamento da GPU, funcionando com a bateria, também é compreensível. A baixa cobertura do espaço de cores da tela não deve ser vista de forma negativa com um aparelho destinado aos negócios, mas deve ser mencionado, no entanto. Finalmente, é preciso criticar o período de garantia padrão, um ano não é suficiente.
O vencedor do preço/desempenho: Com um preço baixo e recursos legados, como uma porta VGA e uma bateria substituível, o L470 é um portátil empresarial interessante de 14 polegadas.
Apesar destas desvantagens, o L470 merece uma recomendação como um pacote de preço/desempenho atraente. Contra o seu concorrente interno mais próximo, o E470, o L470, um pouco mais caro, pode distinguir-se através de uma porta de estação docking dedicada, uma porta VGA e a bateria substituível. No entanto, com o Nvidia GeForce 940MX, o E470 é mais interessante para os gamers casuais. Acima de tudo, o L470 derrota os ProBooks 440 e 640 da HP, graças à tela IPS, porque ambos os Probooks vêm com telas TN. O concorrente mais durão é o Dell Latitude 5480, que, em termos de preço, compete mais com o ThinkPad T470 que o L470.
