Why no camera and FM radio in iPad?

Build-in camera and FM radio are two functions we like to have in this coming iPad. Why are they not included?

Three reasons I can think of.

1. Cost. To keep the cost low for first generation of iPad. Half year ago, there a lot of discussion on how much this iPad will be priced. A lot of people expected it will cost from $699 to $999. When last month Steve Jobs announced the iPad, most of people were surprised with the price. Then, people took iPad apart and found out the cost of those parts, and came out the total cost. Now, they are saying, Apple can sell it in even lower price. Without camera and FM, Apple can keep this first generation of iPad low so more people can buy it.

2. Accessory. Without camera and FM radio, Apple and third party can put camera or FM radio on the market as accessories to earn extra money. Looking at iPhone and iPod Touch, accessory is a huge market.

3. Leave room for next generation of iPad. After one or two years, by adding more features such as camera or FM radio to next generation of iPad will get new or existing iPad owner to buy new iPad. Surely, it is not bad thing for Apple.
