I would say that the wide borders/bezels are needed for handheld devices larger than your hand. You can get by without bezels for a phone that fits within the palm of your hand but a tablet or e-reader needs something to hold onto. Having the audio player is for audiobooks and it makes sense to include those in a book device. It doesn't detract from the rest of the reader. The web browser is mainly there to connect to the books stores so you can buy more books. It's not really intended for general web browsing. The main thing keeping Amazon and others investing more in e-readers is the limited market. Some of us appreciate a light, low cost, dedicated device that is focused on the reading process, but that is a minority market. Most people just want to use one device for everything and don't care if it is less suited to reading as long as it is fast, colorful and they don't need another device.
