256 MB of built-in flash memory. This was later increased to 512 MB. The memory card slots were replaced with USB ports on the newer Xbox 360 S models. The Universal Media Remote can be used to control several functions of the console, including the Windows Media Center functions if connected to the network. It communicates with the console via infrared through a receiver port on the front of the console. All standard controllers for the system feature a 2.5 mm headset jack to allow the use of wired headsets for voice chatting. The 2.5mm jack can also accept the chatpad accessory. Various other accessories for the console exist, such as decorative faceplates to change the physical appearance of the console. Physical appearance The physical outline of the original style Xbox 360 is and is similar in form factor to its predecessor. It is slightly slimmer in every dimension and is slightly concave, while the original Xbox was noticeably convex. It comes as standard in either black or white, with other colors available as special editions. It was designed by Astro Studios in cooperation with Hers Experimental Design Laboratory. The original case has a concaveness to it; Astro Studios' president Brett Lovelady said that part of this was to keep an "X" shape to the console when looked at from the front, while it also served to help with cooling the system components, as the narrower section helped the console to "inhale" more air, particularly when placed in the vertical orientation. In June 2010 a redesign of the console, known as the Xbox 360 S, was announced. This version of the console retains the same basic shape but is noticeably smaller and more angular than the original version. It comes as standard in either matte or glossy black; like its predecessor, other colors are available as special editions. The front of the console features a "ring of light" that displays four illuminated quadrants in either red or green (Some special editions replaced the green for blue). When the lights turn red, the console has encountered an error, with the number of sectors illuminated informing the user what category the error falls into. Since the redesign of the console removed the red LEDs, this error reporting system is no longer used. The original Xbox 360 weighs approximately , about 350 grams heavier than the new Xbox.
