Original sentence: A new handheld war has begun with the release of the Nintendo DS and PSP in 2004 and 2005.Both systems support Wi-fi networking or a derivative thereof for local and online multiplayer gaming, with the former already well established, and the latter developing more slowly, in each case.For example, films are being released on the PSP's UMD format, and the system can play video and audio from Sony's Memory Sticks.It also sports a microphone input.It has shown considerable early success, particularly in branching out from the usual core demographic of computer game players due to the intuitivity of the touch screen control system.The DS is the cheaper of the two systems at retail, and has a considerably longer battery life.The PSP is the more technically powerful of the two, considered somewhere between a PSone and PS2, and is advertised as a portable multimedia system, as well as a handheld console (much in the same way as the PS2).The PSP sports a large high-resolution display, and a small analogue stick, as well as standard controller buttons
