Apple iPad pre-orders begin today, with the Wi-Fi version available April 3, and the 3g + Wi-Fi model available in late April. To increase interest in the launch (by that, increase pre-order sales), Apple is providing new information on the iPad’s features. And if you are still sitting on the fence with respect to buying one and which one to buy, we have a few tips that may aid in your choosing the best iPad version for your lifestyle.

New iPad Details Emerge:

• What was previously known as the mute switch on the iPad, similar to the one on the iPhone, is now known as the "screen rotation lock" on Apple's website.

• iBooks will be able to sync free (non-DRM'd) ePub titles in from iTunes, which is good news for people who want to use an existing ePub collection.

• The iPad can indeed use VoiceOver screen-reading for reading pages of books out loud, meaning it will be more directly integrated into iBooks.

• To make the iPad more external camera friendly, Google's "Terrain", support for additional photo formats (AVI and MJPEG) and native uploads to Facebook will be available.

Apple also announced that those who sign up for the 250MB iPad data plan will receive pop-up alerts when they're running short on data, similar to battery warnings, at the 20 percent, 10 percent and zero marks. There's an account management pane that lets you sign up for or cancel service, add another 250MB, or swap to an unlimited plan.
