Personally I have nothing against sony and/or its products however, PC Magazine (a well respected computer industry trade magazine) tells me the only fault to the Sony readers is that they are really expensive. That said it looks like you will be buying readers for a while now so the cost is going to be a problem and recall what I said above. Perhaps a Kobo would be more in tune with what you need since its: a) cheaper and 2) seems to specialize in simplicty. You will still be able to share books with a free software package called Calibre which will translate between the different file formats that you will need.
If you are buying a book from sony that you can see all of your family reading on their individual readers, you download the book and use calibre to convert it to epub format. I understand that Sony has no problem with epub format, neither does Kobo.
