How necessary is the SD slot anyway? ereaders usually have ~3.5 GB of available storage (factoring in the dedicated OS partition). You can fit thousands of books on that, assuming an average 1MB per book.
That being said, the latest Kindles cannot be jailbroken without hardware modding, and the jailbreak is needed to manage collections with calibre.
If you want to manage collections with calibre, you will want to get a Kobo, they support this off the shelf. (And they have an SD slot anyway.)
