In my experience , there is a problem with using the normal 6 inch ereader for technical documents . I ' m using an Kobo Glo ereader and run into a few problems with the last coding humble bundle . Most formatting is fine , but the code is often misformatted . Sometimes the Kobo trys to break the code into smaller parts to fit the screenspace and then it is not really comprehensive anymore . Not a big problem , but sometimes it just cuts the lines off if they are too long , not finishing them so that you miss a good portion of the line . Also statistical graphics , enumerations and tables are sometimes distorted . Otherwise is the Kobo Glo a great ereader wich works nearly flawless with Calibre under Linux . I use them together for three years now and did not encounter any major problems . Now there is just an additional 10 inch tablet in my setup , wich solves my problems with technical and scientific documents .
