If that 5G iPod's screen is a bit small for extended video viewing, nestle it into the Sonic Impact K1 with its 7-inch widescreen display and solve the problem pronto. It has integrated speakers and a touch-sensitive interface, but we're a bit worried about the stretched video in the picture here, where the iPod's 4x3 video is unattractively turned into 16x9. Hopefully, that will be adjustable.
However, anything that can actually add 7 inches to anything can't be all bad. It's a shame it costs about the same as a 30GB iPod, though, about $300.
