The last time I traveled with an ultraportable machine that lacked an optical drive for business, I regretted it big time. I needed that optical drive several times to access documents given to me on the road and I was out of luck.
The best feature of the Gateway EC14D07u is the DVD drive crammed into the little machine. That is something that you just don't see in the size range the machine is in very often.
The Gateway EC14D07u also has good performance and battery life, making it a very nice option in the ultraportable crowd, especially for those needing an optical drive.
