One of my favorite classes of notebooks to use is the ultraportable. These machines are some of the more expensive notebooks you can buy, typically thanks to the small screens, powerful CPUs and the lightweight materials they are made from. The ultraportable is the class aimed at the business user needing all day power, the student moving all around a large campus, or a user that just wants a notebook that is small and sexy.Today I have on my test bench one of the latest ultraportable notebooks from Acer called the Acer Aspire TimelineX 1830T-68U118. The TimelineX series is well known for being small and having fantastic battery life. The specs of the Acer Aspire TimelineX 1830T-68U118 look up to par for the series on paper, but time will tell if the machine can pass muster in the real world.Today I will put the notebook through its paces and see how well it performs on the other side of our grueling benchmark regime. At the end of the day we will know if the Acer Aspire TimelineX 1830T-68U118 is all show or if there is an equal amount of go inside the svelte chassis. Read on for all the details.
