The rumored nine-inch Kindle Fire is rumored to sport a high-definition screen with resolution of 1920 by 1200 pixels. If the rumors prove correct, we can lay to rest the older argument that tablets "must" have a specific screen size.
Another rumor has Apple preparing its own seven-inch model, as it appears users are figuring out what to do, and why, on devices with varying screen sizes.
One size, apparently, does not fit all.
