Hi,
I currently have a Sony PRS-T1, I had upgraded to this from a Kindle a couple of years ago as I found the kindle tedious to use when transferring multiple books from a series via Calibre....grouping them in collections was done manually on the device.
The poor old sony is on it's last legs and so I need to replace it! the Kobo Aura and Glo have caught my eye but I am hoping someone can confirm that they have the same functionality that Sony does in the way it handles collections. I often purchase/download a whole series at a time and then as new books are released add to that series and I love that calibre will automatically put the books together when it transfers them to the device....can anyone tell me if Kobo is the same?
I have searched this topic but couldn't find a definitive answer, apologies if this is obvious or I've missed it somewhere in the forums!
Thanks in advance
