Google’s quad-core Nexus 7 made by ASUS is not yet fully available worldwide, but the Internet has already shown some of its accessories that you might want to consider purchasing, once you get your hands on the tablet. The folks at Nordic Hardware were generous, sharing with the world a few slides that confirm the existence of official Nexus 7 accessories that are crafted by ASUS as well. The first of these is the colorful Travel Case which makes use of thermoplastic polyurethane (TPU) material and costs US$ 19.99. The more expensive Premium Cover, priced at US$ 39.99, combines tough materials like leather, microfiber, and glass fiber. The most prominent among the items is the Nexus Dock which features a 3.5mm audio connector and has a micro-USB port, priced at US$ 49.99. According to the slides, the Travel Cover should have been out since July 16, whereas the Premium Cover and Nexus Dock will be released next month.
