I also have both devices and the use case for me is entirely different. The iPhone is designed for consumption. The ui lets you choose what you consume, such as music, video, email etc perfectly. The Eee on the other hand is ideal for creation on the go. It's got a full keyboard, webcam sd reader and usb ports and is lovely for bloggin on the go. It's certainly not a device you'd carry in your pocket all the time like the iPhone. Typical users consume far more than they create.
