Heres my theory: Apple designs both the iPad 1, and 2 but in reverse.. So they design the 2nd generation but closely before the 1st (after getting a general idea of what the iPad will be, of course) This would be an advantage to them, because if they can make an iPad that is drastically thin, light, has amazing battery life, and still @ $499, then they will completely shock the audience. Heres where it gets clever... Apple, knowing the specs of the 2nd gen iPad.. Its price, its max battery life, its price, and does some thinking.. The battery life of the iPad 2, im sure, will just push 8-10 hours, greatly depending on what hardware that needs to power the software is being used (ie games, apps, safari) So Apple designs the ultimate iPad, the iPad 2, and then gos back to the drawing board, and skims some features of it. Now were left with an iPad with more thickness, less hardware, but they will keep the same battery, because the less powerful hardware would mean that the battery will last ultimately longer, but they will still advertise a 10 hour battery life. They also keep the same price, because its still low, and once they release the 2nd gen, the audience, will again, be amazed. So lets summerize this theory.. 1. Apple creates a general idea of what the iPad should be.. 2. They design an iPad in which they can fit quite alof of features into it. 3. The 1st iPad is purposely slimmed of its features, but keeps the same price for profit, and also the battery which would mean it can run longer. 4. Here comes along the 2nd iPad, higher specs, same battery, same price.. and a dramatically thinner design.. This of course completely wows the audience! And who knows, maybe theres an iPad 3 that they already have ready to ship, but arent because they are using this theory.
