Apple's supply chain is expected to start supplying components for a 12.9-inch iPad in late September, ahead of a mid-November release, reports DigiTimes. However, Apple's initial order is said to be a cautious one.
Apple is rather cautious about placing related orders and the initial shipment volume is much lower than most market watchers' expectations, according to sources from the upstream supply chain.
Because they made the same exact versions for the same product no matter the size compared to how Apple does it. If a monitor and keyboard are made together with the entire product being built differently than an iPad, then yes. Why would anyone use OS X without a physical keyboard?
If not, there is an emulator and you can use your iPhone as a trackpad. I believe the app that allows this is called Tabimouse. Really though, zi don't see a point for OS X to run on it. iPad is more resembled to the iPhone because 1. It's not built like a computer, 2. It's nothing more than a tablet with a keyboard add on for better typing (some say but me), 3. Imagine having OS X on iPhone for example.
