The sixth-generation Nano will not force the Shuffle out of Apple's iPod product line, people familiar with Apple's plans are said to claim. The size of the Nano is expected to shrink substantially, according to AppleInsider, to the point of being little larger than a 1.7-inch display -- possibly a touchscreen. Dimensions may be comparable, in fact, to the second-generation Shuffle, creating some duplication. Nevertheless, Apple is claimed to be keeping the Shuffle on as an "entry-level" iPod.
