As Kejistan said, you don't buy an iPhone instead of a computer. Most people are used to phones that can make calls, send messages and little more, so the iPhone is more capable. Tivo is also not a replacement for a computer, but for less capable movie/tv players. Most people may just be browsing the web most of the time, but they also use the computer to copy photos from a camera, make party invitations, etc. Netbooks may not be suitable for running Photoshop and Excel, but they can when you need to. This is why they are so popular.
