* The ARM processor in the iPod touch is a newer revision than the iPhone 3GS's CPU. We still don't know its exact clock speed but it's a definite upgrade from the 2nd Generation iPod touch.
* It has a 1080 mAh battery; what does that mean? Well, it'll get pretty good battery life. Apple's website lists it at 30 hours of music playback.
* The NAND flash memory is manufactured by Samsung and has been split into two chips to achieve the 32GB capacity.
* The wireless chip is from Broadcom. According to their documentation this chip supports 802.11 n as well as 802.11 a/b/g. This is a new move from Apple. Until now, all of the mobile devices have only had g-capable wireless chips. It's possible that this would be enabled in the future, but I wouldn't put money on that.
* Mark this one as rumor fodder: iFixit claims that there is room for a camera at the top of the device. The empty space measures 6mm x 6mm x 3mm. That could easily fit the same style camera as the 5th gen iPod Nano, but they don't believe an iPhone-quality camera would fit because of the limited space.
