Se destacar entre a multidão é bastante difícil, especialmente se estiver competindo contra nomes e marcas estabelecidas. Vamos descobrir se a Acer tem ou não chance no mercado de empresarial de gama baixa contra Probooks, Latitudes e Thinkpads deste mundo, com o TraveMate 449, vamos?

Not all notebooks can be opened 180 degrees.
The TravelMate's colors are businesslike.
The case is made entirely out of plastic ...
... and the base is much more stable than the lid.
Overall, the P449 is fairly similar to the more expensive P648 ...
... from the positioning of the Acer logo ...
... to the exact same hinge design.
The bottom cover is equipped with two maintenance flaps.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
28 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 12 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 58 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.9 ms).
       Response Time 50% Grey to 80% Grey
39 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 17 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (43 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 25000 Hz70 % brightness setting

The display backlight flickers at 25000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 70 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5559 (minimum: 43 - maximum: 142900) Hz was measured.

Portáteis empresariais acessíveis como a nossa unidade em questão, às vezes são descritos como o "pão e manteiga" do mercado de portáteis pelos fabricantes: não particularmente excitante, mas um campeão de vendas. Afastar-se da concorrência é bastante difícil, e a maioria dos aparelhos se perde entre a multidão. Este também é o caso do TravelMate P449: portátil empresarial sólido, mas nada extravagante.

Particularmente simpático foi o muito bom touchpad do P449. Um touchpad medíocre ou ruim pode arruinar toda a experiência e, nós damos as boas-vindas ao fato de que a maioria dos fabricantes vem prestando cada vez mais atenção ao touchpad nos últimos anos. Considerando que alguns fabricantes, como a HP, ainda estão equipando seus portáteis empresariais com painéis TN inferiores e painéis mesquinhos, o painel  IPS do P449 é definitivamente uma vantagem. Também gostamos das baixas temperaturas de superfície do P449 e do veloz SSD PCIe com o qual nenhum dos concorrentes estava equipado.

Não é de primeira qualidade, mas não está mal. O TravelMate P449 é uma obra suave, porém, bem feita.

Lamentavelmente, o dinheiro gasto por um lado deve retirado de outro e, em troca do veloz SSD PCIe, o P449 está equipado com um leitor de cartões SD muito lento e mal projetado. Além disso, também não gostamos o design alterado do teclado, e porque o P449 tem um slot para uma unidade de 2,5 polegadas, mas faltam os conectores, continua sendo um mistério, igual que a ventoinha. Dadas as baixas temperaturas, nós realmente não vemos motivo pelo qual ventoinha não é desativada completamente quando o aparelho esta no modo inativo e sob uso leve. Como com todos os aparelhos neste segmento de mercado, o espaço de cores da tela foi bastante pobre. A duração da bateria foi muito pobre, e todos os outros aparelhos duraram muito mais em nossos testes.

Em resumo, o TravelMate P449 ainda pode ser um aparelho agradável, desde que se acostume ao teclado. No entanto, nenhum de seus concorrentes foi perfeito, mas alguns oferecem algumas vantagens, como baterias removíveis ou GPUs dedicadas.
