The prices of USB flash drives are relatively low nowadays. For users who need a method of transferring files between computers besides using the internet or CD-Rs, flash drives are a very attractive and practical solution. They can also be "cool" to show off to computer illiterate coworkers who have never seen such things before. For whatever reason you think you might need one of these drives, they are cheap now and probably will continue to get cheaper to some degree as flash memory prices fall.
