Playstation 3 Hardware
PS3 supports up to seven connected bluetooth devices which can be a mix of game controllers or other bluetooth devices such as compatible headsets and keyboards. Connecting to your LAN is accomplished through the integrated gigabit ethernet adapter, or an optional wireless adapter for the 20GB model, and the integrated B/G adapter on the 60GB model.
Both DVD playback and high-definition Blu-Ray playback are supported standard, making the PS3 one of the least expensive Blu-Ray players on the market. DVD upconversion is also possible but only available through an HDMI connection.
Composite, S-Video, Component and HDMI are all supported output types of the PS3 with a variety of resolutions available such as 720p, 1080i, and 1080p. Both stereo and optical output are supported with many formats supported including Dolby Surround Sound and uncompressed LCPM.
Out of the box the PS3 is the most backwards compatible out of all the systems, as almost every single Playstation 1 and Playstation 2 game plays properly. Early North American and Japanese consoles have PS2 compatibility built into the hardware with all European versions using software emulation. Later versions of the PS3 in all territories are expected to use software emulation instead of hardware.
Another feature that is unique to the PS3 is the ability to swap out the included hard drive with any standard SATA 2.5" laptop drive. Any SATA drive can connect and be used with the PS3, however the slot can only fit a 2.5" drive.
Playstation 3 System Software
Similar to the Playstation Portable (PSP) the PS3 uses the Cross Media Bar (XMB) interface to access the different functions and services the PS3 offers. Similar to the Xbox 360 the PS3 provides a vast array of services right out of the box that span the gamut of game playing and multimedia playback.
An online distribution system, known as the Playstation Store, is accessible for free which lets users download game demos, Playstation Network titles, movie and game trailers, as well as extra software to enhance the PS3 experience. One of these free software packages is Folding@home. In Fall of 2007 Sony will be releasing Playstation Home which is a Second Life kind of virtual world where users have properties that they can customize and share with their friends.
A feature that is totally unique to the PS3 is the ability to load on custom operating systems. Linux is the only operating system that has been developed to work with the PS3 with a few flavours being available, the most popular being Yellow Dog Linux which has a distribution that is customized specifically for the PS3.
