There must be more people who prefer 3 x 4 or 4 x 3 for reading. After all, almost all of the eInk devices from the major players use a 600 x 800 screen (which is 3 x 4). The only player to use a longer screen recently was Sony in their PRS-900 and PRS-950, both of which are discontinued. Thus only 600 x 800 screens are currently being used for 6 inch screens. I think the probably soon to be extinct Kindle DX is also 3 x 4 ratio though a larger screen overall.
