Apple today refreshed its iPod touch lineup, discontinuing the silver 16GB iPod touch and replacing it with a new $199 model. Hardware-wise, the new entry-level iPod touch is identical to the existing 32 GB and 64 GB models and includes both a rear camera and an assortment of color choices. The iPod is a significant improvement over the now retired $229 model, which was available in silver only and shipped without a rear camera. You can purchase the new 16GB iPod touch for $199 from Apple’s online store and its brick-and-mortar retail stores starting today.
