I don't have The new iPad, but I've been reading about some cases where the device has been getting really warm. Heat is never a good thing when it comes to mobile electronics. After all, heat can damage the internal components and degrade long-term battery life. (and if you're a guy, don't place that warm iPad on your lap too long... )
Most people refer to The new iPad as the "iPad 3." Let's wait to see how many other people report heat problems on their new device.
