Microsoft Xbox
The Xbox was Microsoft's first game console, released on November 15, 2001. It was Microsoft's first independent venture into the console arena, after having collaborated with Sega in porting Windows CE to the Sega Dreamcast console. Notable launch titles for the console include Amped, Dead or Alive 3, Halo: Combat Evolved, Oddworld: Munch's Oddysee, and Project Gotham Racing.
Hardware
Microsoft built the Xbox around industry-standard PC hardware, unlike the traditionally proprietary design of nearly all other gaming consoles.
The inclusion of the hard disk not only serves as a disk cache for faster game loading times, it also allows users to download new content for their games from Xbox Live and copy music from standard Audio CDs so players can replace the soundtrack of Xbox games.
Although the Xbox is based on commodity PC hardware and runs a stripped-down version of the Windows 2000 kernel using APIs based largely on DirectX, it incorporates restrictions designed to prevent uses not approved by Microsoft. The Xbox does not use Windows CE due to Microsoft internal politics at the time, as well as limited support in Windows CE for DirectX.
The Xbox itself is much larger and heavier than its contemporaries. Mostly, this is due to a large tray-loading DVD-ROM drive and the standard-size 3.5" hard drive. Despite managing to be smaller and lighter than similar commodity PCs, the Xbox has found itself a target of mild derision, as gamers poke fun at it for things like a warning in the Xbox manual that a falling Xbox "could cause serious injury" to a small child or pet. While some elements of the Xbox's design, like breakaway cables for the controllers to prevent the console from being yanked from the shelf, take the size into account, it has undoubtedly hurt the system's sales to the space-conscious Japanese.
Another common complaint about the system was that the original game controller design was seen as too large for some people. For the Japanese Xbox launch, a smaller controller was introduced, a design which was subsequently released in other markets as the "Controller S", which eventually replaced the original design. Currently, all Xbox consoles come with a "Controller S", and the original version of the controller (also known as "The Duke") is no longer sold.

Networking
Ethernet (Xbox Live) Cable: A Cat 5 cable for connecting the Xbox to a broadband modem or router (note that there is no "official" Xbox Live cable; any PC ethernet cable can be used)
Xbox Wireless Adapter: a wireless bridge which converts data running through an ethernet cable to a wireless (802.11b or 802.11g) signal to connect to a wireless LAN. While the official Wireless Adapter guarantees compatibility with the Xbox, almost any wireless bridge can be used.
Xbox Live Starter Kit: A subscription and installation pack for the Xbox Live service, as well as a headset (with monaural earpiece and microphone) that connects to a control box that plugs into the top expansion slot of a controller. The headset can in fact be replaced with most standard earpiece-and-microphone headsets; headset specialist Plantronics produce various officially-licensed headsets, including a special-edition headset for Halo 2.
System Link Cable: A Cat 5 crossover cable for connecting together two to four consoles, for up to 16 total players. This functionality is similar to Sega's DirectLink for Sega Saturn.
