The next-gen iPad might kill various competitors since everyone is launching a their first-gen tablets now and that’s one more reason for Apple to come out with the iPad 2 when rivals will only have launched their first Tab, PlayBook, or any other device.
In other words, the next iPad could have a smaller bezel--the black area around the screen, and it won't teeter-totter or slide around when you press on something along the edges.
MacOtakara says a more substantial change to the exterior will be the location of the speaker, which could be moved from the side of the unit to the back. Presumably, this could keep someone who is holding the device in either portrait or landscape mode less of a chance of blocking the speaker holes. MacOtakara also says this speaker would be wide range, which could offer more evenly distributed audio at off-angle viewing.
One other small tweak MacOtakara is reporting is a change in the location to the iPad's ambient light sensor, which is moving from the front of the unit to the back. This would be a fairly large departure in location given where Apple keeps it on the current iPad, as well as on iPhones, iPods, iMacs, and its MacBook Pro and Air lines.
