I am about to purchase a new Paperwhite Signature edition and then started worrying....after all that Amazon has done to disrupt our Calibre usage, will I still be able to download amazon ebooks that I already have on my Calibre?
I know this sounds simple, but I am worried . I have many wonderful books from many years on my calibre on my pc and hope I will still be able to get to them!

I am sure most members here know the answer to my question and please answer if you will.....will I still be able to transfer my amazon book files through calibre to my new kindle?
Or should I just cancel ordering this newest signature edition?
