To me at least, it seems incomprehensible why someone would choose the inferior iBooks
reading experience just because Marvin won't directly load all 2000 books from Dropbox for you.
In fact, I've always advocated not storing hundreds of books directly on our e-reader devices, but preferably in the cloud, in those Calibre folders. They are always at hand there, in case you need them. Or is anyone actually reading 2000 books simultaneously?
Take the analogy with movies, for example: would you reasonably expect from the iPad to be able to store all Alfred Hitchcock movies on it permanently, thus wasting the iPad's limited, precious storage space?
Nope, I suppose you wouldn't want to do that... as long as any Hitchcock movie is easily accessible to you at the touch of your finger (be it through Apple's store, or whatever) -- then there's no reason to store all those movies directly and permanently on your handheld device.
But the main point comes down to this: you seem to be willing to sacrifice a superior
reading experience for the sake of an automated book-loading or book-storing experience.
But let me ask you: which of the two is really essential here? As to me, I spend about 15 seconds
loading an e-book from a Calibre folder stored in SugarSync... and then I spend 10 or 15 hours
reading that book.
So, I may spend 0.01% of my time
loading or
storing a book, and I spend the remaing 99.99% of my time actually
reading that book.
What you're saying is, you're willing to exchange 99.99% of superior
reading experience for 0.01% of better book-loading or book-storing experience that iBooks (just maybe!) offers.
This doesn't quite make sense to me.
