Apple Announces 4-Inch iPod Touch, Multitouch iPod Nano
Apple is promising 40 hours of music playback, and 8 hours of video, slightly increased over the 4th generation Touch. The back camera is much improved to a 5-megapixel, backside illuminated, f/2.4, 5-element lens, with the same sapphire crystal lens cover as the iPhone 5. The front camera is also upgraded to a 720p camera. The new iPod touch also supports the new Panaroma feature and also includes Siri.
Finally, there's hidden feature on the back of the new iPod Touch, called the Loop. It's designed to hook to a wrist-strap for added security.
The new iPod touch comes in five colors and will be available in October at $299 (32GB) and $399 (64GB). The 4th Generation iPod Touch will remain at $199 (16GB). Preorders for the new iPod Touch begin September 14th.
Apple also announced a radically redesigned iPod nano. The new iPod nano has a 2.5" screen and multi-touch interface. The design shares a lot of cues from the iPhone with the inclusion of a front Home button. The iPod nano includes an FM tuner, widescreen video, pedometer, Bluetooth, and the new Lightning connector.
The new iPod nano comes in 7 colors and will be available in October for $149. Preorders for the new iPod Nano begin September 14th.
The iPod Shuffle was upgraded with new color choices, but the same $49 pricing and 2GB capacity.
