One of the new cool features of the up-coming version of Windows Media Center is the ability to syncronize with these new devices called the Portable Media Centers. I was able to see some of this new gadgets at a recent trip to Redmond and believe they are super cool. If you like your IPod you will fall love this new devices.
These devices can store up to 80 hours of video, be that TV, movies or home movies, over 10,000 songs and up to 100,000 photos.
I saw the following two models (the links take you to Amazon.com and you can see detailed specs and pre-order details):
The Samsung YH-299 - 20GB, 3.5” LCD and USB 2.0

And the Creative Labs Zen - 20 GB, 3.8“ LCD
