Yes, I too had a Sony ereader for years, and it was nice fitting it in my jacket pocket.
But the reality is that most book pages are larger than 6", and if I found myself preferring the book because of the size, what's the point of an ereader? I first switched to 7", which was better, but not good enough. 8" is great, though.

How many hours will the battery last while on? And how does that compare to a similar sized tablet?
Page size isn't that big a deal when the text reflows and can be resized as desired, except for when one wants to view a map or diagram. Before I got my Scribe I'd fire up the Kindle app on my tablet (or convertible) for such usages at need.
I can read and take notes and even web browse (insofar as browsing is supported on the Kindle browser) for hours on end and barely budge the battery percentage, while a tablet w/ an LCD screen would run through half or more of its charge for similar usage.
