Thanks HarryT and Johanm
Very few of my ebooks are DRM protected, a couple in Mobi-format and a couple in .lit format.
My PDF-files are mostly A4 size. They are for school-work and are converted from powerpoint-slides (with some text and pictures, or tables or scans from books
Ereader/palm is the format I get when buying books from ereader.com. I don't know what you mean by extention Johanm
I have a couple of weeks untill I buy it as I'm waiting until I get paid.
