CD and DVD drives
Most notebooks, even budget systems, now include a DVD/CDRW combo drive (either built in to the laptop or external and connected via USB) for burning discs and watching movies on the road. Some higher-end notebooks offer DVD burners, which let you store large amounts of information on one disc; double-layer DVD burners can pack even more data on a single disc. A few models, like the Toshiba Qosmio G30 and Sony VAIO VGN-AR28GP, even offer next-generation optical formats in the form of HD-DVD and Blu-ray, respectively.
