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.
Which doesn't really have anything to do with what I posted, which was that paper mass market books are closer to the 16:9 ratio (I think). Most people take what's available and eInk screens are predominantly manufactured in 3:4, but that doesn't necessarily make the other ratio bad, unwanted or anything else.
Personally I've tried both and I guess it doesn't make much difference to me.
