Steven Johnson was saying, just a couple of weeks ago:
Because what I need now in my iPod is not more storage space, or Mini-style color designs -- what I need is wi-fi. I want my iPod to double as an audio remote control when I'm sitting in my living room. I want to be able to call up any song on any computer in home network, and direct it to any set of speakers, right from the iPod scrollwheel.
I don't know that it's gotten to that point just yet, but the folks at engadget (a link caught at boingboing) now have a how-to column about turning your iPod into a universal infrared remote control. Pretty speedy service, and damn cool, to boot.
