Continuing with all things Eeepc, I got a Tekkeon MP3450 external battery. So far, seriously rocks. Along with the Eeepc battery I figure I can get something like 8 full hours. The Tekkeon is relatively small, weighs about a pound. See side pic, no one seems to show it in comparison with an eeepc, and for Eeepc to MacBook photo, see previous post.
