Mine wore out quickly; switched to an optical memorex, and it still runs well after a year. Recently got a Inland wireless mouse and keyboard combo for $5 after rebate at frys, and they work well.
compaq and hp oem keyboards and mice suck d*ck but the dell oem keyboards and mice (at least the older ones) are good especially since some of the mice were the same as logitech models except the dEll logo on top! logitech and microsoft make decent kbds and mice
