Here’s yet another update (courtesy of Gizmodo) from Steve Jobs’ keynote earlier today: the 2nd-generation iPod Nano. Upgrades include new lightweight aluminum casing, 2GB ($149); 4GB ($199); 8GB ($249) capacities, and an impressive 24-hour battery life. We’ll keep you posted as more information becomes available. More pictures and a video after the jump.

New packaging is 52% less volume than the old iPod nano. It’s more “environmentally friendly”. The new nano works with the charger, the armband, lanyard, and works with the Nike Shoe
