The Apple Store went down this morning for the iPad pre-order update. It’s back up, giving the world access to the highest profile tablet we’ve yet seen. Apple has imposed a pre-order limit of two per customer, which has me wondering whether the company expects the kind of quantity problems that lead to mad eBay selloffs.

The store update also revealed pricing on iPad accessories. That nifty little keyboard dock will run $69 while a regular dock is just $29. You can also get the official iPad case for $39. The update also revealed a nice new feature on the iPad – screen orientation lock. It’s a great idea for anyone hoping to use the iPad as an ereader. It allows you to hold the device in any position and maintain the screen. The auto-flip has frustrated me on the iPhone on occasion so its nice to see the problem addressed for a device designed for reading.

Prices start at $499.00. Will you be getting one?

More clues have surfaced that suggest Apple is indeed planning a camera for the iPad. We’ve already seen that there is space in the chassis to host a small camera, now MacRumors says there is software to support video conferencing as well. The latest SDK has accept and decline commands for video chat services.

The specific API threads reveal support for at least testing front-facing cameras, zoom, and an LED flash (as in a camera, not the software). 9to5 Mac also uncovered the following buttons for video chat.

The size of the actual image suggests a screen the width of the iPad’s, so it may not be for the iPhone as well. It could also simply be for internal testing, but my guess is that, as with the iPhone, the later generations of the iPad will be where the magic is at. If anything, I’d bet Apple is waiting on a better video camera to put into the iPad.
