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.
