Today Apple released the new iPod nano, which comes in black as well as white, and in 2 GB and 4 GB versions. It also has a color screen and a clickwheel.

Here’s one thing to note, from a review:
Not Quite a Full-Grown iPod
Although the iPod nano can display pictures and slideshows like today’s color iPods, it doesn’t have all the capabilities of these iPods. For example, you’ll find no TV Out commands in its Slideshow Settings window because it can’t project pictures to an attached television. Also, it doesn’t work with Apple’s iPod Camera
Connector or Belkin’s Media Reader, which means you can’t upload pictures to it. And although the Diagnostic Screen shows a LineIn test, current iPod microphones require a connection to the Remote Control port as well, which is missing on the nano.
Black iPod nano
Will I be getting one? Probably not. I’m happy with my Creative MuVo N200, and I recommend it to anyone who wants line-in, a built-in microphone, FM radio, and FM recording. In addition, I’m saving up for those Intel PowerBooks 
How to Upload Pictures to the iPod nano
It has to be done in iTunes, rather than dragging and dropping through the Windows interface. Go to Preferences -> Photos. Your iPod needs to be plugged in. From there, you can select which photos to synchronize.
On XP, the problem with the ‘Locked’ file is caused when syncronising photos. iTunes creates a directory called “iPod Photo Cache” inside the directory from where you are synchronising your photos. Simply close iTunes, delete this directory and restart. If you cannot find this directory, you need to check our Explorer settings and ’show’ all hidden directories and files. Naturally, iTunes will have to reformat and re-synch all the photos, but it works.
