With Netbooks gaining in the popularity, it is no longer a novelty or gadget in the computer world. In fact, it looks like it is here to stay. The Netbooks are designed to be highly portable and have a long battery life. As a result, Netbooks usually have to make a sacrifice by forgoing the optical drive. Although many people probably will be okay with the omission of the optical drive in place for a small portable computer, the truth is that there are times when having an optical drive can be useful even if you use your system on the go. Realizing such demand, HornetTek has launched the D-Slim, a portable optical drive that is designed to be used for those who need an external optical drive on the go.
