The lack of justification on the pre-900 models was a point of contention with many of us. That and the fact that the 300 and 600 placed a tiny page number in the right margin. Sony could have fixed those minor issues with a firmware update, but chose instead to wait and introduce newer models. There are two or more alternate formwares available for the 300 that might address those issues. You can search for them on this forum. One is PRS+. I cannot remember the name of the other one.
