BIOS Magazine posted a review on the Sony Blu-Ray Burner (BWU-100A)

Sony's BWU-100A represents a significant leap in storage technology. The BWU-100A offers relatively mediocre Blu-ray recording performance, but it's really a tool for content authoring. It is suitable for high-end home-theatre systems, too, but the price will deter most movie buffs. Overall Sony has created a typically well-mannered product that covers all the bases - CD burning, DVD recording and Blu-ray movie playback, as well as Blu-ray disc recording. The downside? It's pricey (expect similar drives to cost half as much in a year or so) and there's still the pesky Blu-ray versus HD-DVD question, which may take several more years to iron out. For enthusiasts looking for Blu-ray playback on the PC, it's a good start.
