Contra
O Acer TravelMate P449 encaixa na classificação de "Trabalhador de talentos múltiplos e mestre em nenhum". É um aparelho bastante completo que traz muito para a mesa. Acerta em cheio quando se trata do tamanho; o chassi é pequeno e a iluminação suficiente para ser carregado com facilidade, mas a tela ainda é suficientemente grande para multitarefas e trabalho de escritório. A carcaça é atraente e profissional, o teclado se sente ótimo, e o desempenho é mais que adequado para o trabalho de escritório. A tela oferece alto contraste e ótimas cores. A ventoinha é notória somente sob uso intenso, mas as temperaturas são bem gerenciadas e o aparelho permanece frio, inclusive sob uso intenso. A seleção de portas é generosa com 5 portas USB, 2 opções de tela, e uma porta ethernet, e a bateria pode sobreviver todo um dia útil.
O Acer TravelMate P449 é uma boa opção para profissionais que precisam de uma máquina portável e duradoura. Apesar de algumas desvantagens, é uma ótima opção para os guerreiros da estrada com baixo orçamento.
O TravelMate faz alguns sacrifícios para atingir a faixa de preços competitiva. A bela carcaça é fina e se sente barata, portanto, a sua durabilidade é uma preocupação. O touchpad é inconsistente e frustrante de usar, enquanto o leitor de digitais é quase inutilizável. A tela é escura e quase inútil em ambientes claros. A maioria das opções de conexão é lenta ou ultrapassada, e a CPU Skylake está desatualizada e tem afogamentos pesados.
Apesar dessas desvantagens, o Acer TravelMate P449-M-7407 continua sendo uma opção atraente no mercado empresarial sub $1000. No entanto, o preço do Lenovo ThinkPad E470 é difícil de ignorar. Por cerca de $720, o E470 oferece melhor desempenho e qualidade de construção, durações de bateria similares, uma boa tela IPS, e uma GPU dedicada. Por $130 a mais, o ThinkPad pode ser equipado com um Kaby Lake i7-7500U e 16 GB de RAM. Tenha em mente que esses modelos não vem com um SO e podem estar disponível somente em mercados educativos. O ThinkPad E470 é uma sólida recomendação sobre o TravelMate. No entanto, se o E470 não estiver disponível, o P449 é uma ótima segunda escolha.
