Samsung’s Series 5 Ultra is one of the few ultrabooks with a DVD drive, which the company added in response to customer feedback. (The Samsung representative I spoke to described it as a “security blanket” for people who are afraid to abandon optical media entirely.) Nonetheless, the Series 5 Ultra maintains a slim profile of 0.82 in. thick. It’s launching on Jan. 30 for $899 and up. (Details from Samsung)
