Digital Home Thoughts: Netbooks and e-Readers are Happy Together

"The enTourage eDGe™ is the world’s first dualbook, combining the functions of an e-reader, netbook, notepad, and audio/video recorder and player in one. It’s a comprehensive device that lets you read e-books, surf the Internet, take digital notes, send emails and instant messages, watch movies and listen to music anywhere, at any time. This is nothing you've ever seen before!"

Mashups are great. Pairing up two things into something new and exciting helps spur development and creativity. However, I am not sure I am sold on the enTourage eDGe. It sounds like a great concept in some ways. If the mood for reading? Just use the e-reader part and get a long battery life. Need to look up a few things about what you have read? Power on the netbook side and check it out. It sounds nice, but something seems lacking. It feels like I am carrying around two devices that would be almost as effective if it was just one device. Why not just make the screen of a slate netbook capable of flipping between e-ink and LCD? Or if you are going to have dual displays, why not make the whole thing under one operating system and interface? It almost seems that it would be just as good to buy an iPad, and a Kindle, and duct tape them together. Please, can someone show me what I am missing here?
