MSI has begun pushing accessories for their very new Wind netbook, with the introduction of an external optical drive. The drive is designed, aesthetically, to match the Wind, along with being a fairly small drive in general. From a technical standpoint it's not particularly special, offering the same features that just about any CD/DVD combo drive would. It can read and write CDs, DVDs, Dual-layer DVDs and other formats as well. One advantage is the lack of an external power adapter, which helps maintain the “liteness” and clean feel of the MSI Wind.
The drive will be available in a few weeks. There's no mention if MSI has plans to introduce an external Blu-ray drive as well.
