I tried PDFRead to convert some of my pdf files to imp2 format. Unfortunately, I have to use the landscape mode just to be able to read it on my EBW1150. I always prefer the portrait mode but the result is hardly readable. Even on landscape mode, sometimes the text cannot be read. I also noticed that using PDFRead, the file is bloated to several megabytes. I tried experimenting using Mobipocket Creator. I first convert my pdf files ( with images) to mobipocket format ( prc) using Creator then use Mobi2IMP to convert to imp. The result is outstanding ( for me at least). Not only can I read in portrait mode but the final file is a just a few megabytes.
