Amazon.com : Portable Media Centers Amazon has a section on Portable Media Center devices, including an faq etc. The two devices offered for sale (both now with availability status "This item has not yet been released. You may order it now and we will ship it to you when it arrives.") are #6 and #8 on Amazon's "Early Adopter Product in Audio & Video" program as I type this. (Items 1, 2, 3, and 5 on the list are iPods at the moment...)
I plan to wait to see real-world battery life and other test dimensions before putting one of these on my holiday wish-list.
