25.Can I stream media to my 360?
Yes. The 2 most popular pieces of software (if you dont have media center edition of xp or vista, 7 ultimate) that are used to stream audio and video to the 360 are WMP11 and TVersity. Both work great and there are guides all over the net on how to set up streaming to the 360. Links will be provided soon.
26. What is RROD?
RROD is the term referred to when the xbox 360 displays 3 flashing lights in the ring of light on the console, RROD usually indicates a "general hardware failure" (often referred to as a "red ring of death" or "Red ring of Doom) many sources claim that the RROD occurs due to the warping of the 360 mainboard as a result of high heat. many people have fixed their rrod consoles through replacing the Xclamps and overheating the GPU or wrapping a towel around the console and overheating it. Doing any of these is not recommended as it will void the warranty on your console and most are just temporary fixes. The current Xbox 360 S model indicates system overheating when the console's power button begins to flash red, unlike previous models where the first and third quadrant of the ring would light up red around the power button if overheating occurred

27. Are there any special Edition 360's ?
Yes.On a few occasions, Microsoft has produced special editions of the console, usually to coincide with the release of a major product. These special editions are typically custom-colored Xbox 360 models, and are produced in limited numbers. There was the Halo 3 Special Edition of the console, released September 16, 2007. It sports a Halo 3 theme on the console, wired headset, and wireless controller, and play and charge kit. Other than the unique "Spartan green and gold" color scheme, exclusive dashboard theme and downloads, its features where identical to that of the Premium systems. To promote The Simpsons Movie, Microsoft also created a specially-designed, yellow Xbox 360 console. This configuration was also based on the Xbox 360 Premium, with the only difference being the color scheme of the Xbox 360 console and wireless controller. Microsoft also produced a limited edition Dark knight 360 also based on the Premium model and was only available in certain Asian countries.

28. What CPU does the Xbox 360 use ? is it a PC CPU like the Original Xbox ?
NO. The Xbox 360 CPU, internally codenamed "Waternoose" by IBM and "XCPU" by Microsoft is based on IBM's PowerPC technology, consisting of 3 independent cores on a single chip. Each of the cores has two symmetric hardware threads (SMT), for a total of six hardware threads available to games. The cores of the Xbox 360 CPU are slightly modified versions of the PPE in the Cell processor which was designed specifically for the PlayStation 3.
The processors are labelled "XCPU" on the packaging and are manufactured by Chartered. Chartered reduced the fabrication process in 2007 to 65 nm, thus reducing manufacturing costs for Microsoft.
The Xbox 360 S introduced the XCGPU, which integrates the Xenon CPU and the Xenos GPU onto the same die, and the eDRAM into the same package. The XCGPU follows the trend started with the integrated EE+GS in PlayStation 2 Slimline, combining CPU, GPU, memory controllers and IO in a single cost-reduced chip. It also contains a "front side bus replacement block" that connects the CPU and GPU internally in exactly the same manner as the front side bus would have done when the CPU and GPU were separate chips, so that the XCGPU doesn't change the hardware characteristics of the Xbox 360.
XCGPU contains 372 million transistors and is manufactured by GlobalFoundries on a 45 nm process. Compared to the original chipset in the Xbox 360 the combined power requirements are reduced by 60% and the physical chip area by 50%.
The name "Xenon" was repurposed from the code name for the Xbox 360 in early development.
29. Can I run Homebrew applications on my Xbox 360 ?
Yes and No. The xbox 360 cannot run homebrew applications due to the implications of piracy, if people we're able to create homebrew applications then they might create programs to emulate other consoles such as those from rival competitor's or they would create HDD loaders for games etc. Microsoft learned from this during it's original xbox thus with the xbox 360 they have created a hardware level DRM system which restricts the console from running unsigned code, the only Legal xbox 360's that can run unsigned code are the dev kits which the developer's have. currently hackers use a method known as Jtagging to run Homebrew software on their consoles however the risk involved is too great for most people to try as it is illegal, voids the warranty on your console and you can face an 8000 year ban on Xbox Live.
30. When is the xbox 360 being replaced ?
No one knows exactly but rumours circulating the internet are that Microsoft have already started provisional development of the successor to the 360. Current speculation from the industry is that microsoft will replace the xbox 360 during 2012-2013 which will effectively give it a 7-8 year lifespan. microsoft has indicate however that the 360 will be supported well into 2015, probably not as a primary console but it will still have software support from them.

which according to industry analysts indicate that Microsoft is still willing to support the 360 as it's primary console for the next possible 4-5 years.
