Is anyone using a a Kindle Paperwhite device - in particular with PDF files? I have a standard Kindle (4?) with which I'm generally very happy. However - it is very clumsy at handling PDF files. Since my main use for the Kindle is to keep a library of old books (song-related and other) , many of which are freely available online, handling PDFs is important. Conversion of such texts to other formats is often very clumsy.

My local store is out of stock - I think there's an improved version either just out or about to appear... so I can't experiment directly for now.

Regards
p.s. Incidentally, I use the Calibre freeware to organise my Kindle library - it's excellent.
