The ATO iSee 360i was introduced at CES 2006 as a revolutionary iPod accessory that essentially turns your iPod into a portable digital video recorder—even models that aren't video-capable on their own. Not all models are supported, however. Instead, you're limited to 20GB fourth-generation and 30GB fifth-gen models, as well as the iPod mini and nano (with optional $20 adapter). Since the device does not pick up digital video copy protection (including Macrovision), don't even try to use the iSee to record and distribute copyrighted material. One of the iSee's biggest limitations is that it works only with Microsoft Windows–formatted iPods, since the included Windows-only software is required for prepping your iPod for use with the iSee.
