Forget the cell phone, the Aeronix ZipIt instant messaging handheld is truly the classroom killer teacher's have been having nightmares about. Just $99, the only good thing is that the ZipIt piggybacks right onto wireless networks, so if there's none around, you're out of luck. Connects to 802.11b wireless networks and hot spots and can log onto AIM, MSN and Yahoo networks—all at the same time if you're so inclined. Just 6.1 ounces, it's got a black-and-white screen and OS upgrades are automatically downloaded when available.
