It seems that Apple added a little something extra to the iPad for the launch — Screen rotation lock. According to the company’s Web site, which was updated on Friday to take pre-orders, a button on the side of the iPad will lock the device’s orientation. This means that if you want the screen to stay in portrait, it won’t move when you turn it sideways.

I know after writing my first impressions of the iPad, many people emailed asking if it was possible to lock the orientation, so it’s obviously something people have been thinking about.

Apple is taking pre-orders for the iPad today. According to AppleInsider, Apple is limiting customers to two iPads per person.
