When tablets, slates and ultrabooks first launched a few years ago, the lack of a DVD drive were a problem for some. Those who are users of the MacBook Air may have bought a Superdrive for the same reason, we’re just not quite in the era when we can do without an optical drive just yet. This week, Samsung launched the latest, ultrathin and very elegantly designed Samsung SE-218BB, at just 14mm thick, its also 8% lighter than your average external DVD drive.
