New technology has always fascinated me, that is one of the reasons why I choose to write about these new ereaders. Ereaders are machines meant for reading ebooks and epapers. Three different ereaders are presented in this ARBETE. I have looked into what functions the iPad and the iPhone have as ereaders. Do you help nature if you read an ebook? Only after you have read 33 ebooks on the ereader. Are all books available in electronic format? I go through how the electronic ink works. I had a test group testing the Sony Reader PRS600 and the majority of them did like to read from it. In Finland the libraries have started to lend out ereaders and the publishing companies will publish ebook in the autumn 2010. There are over 30 000 available free ebooks on the internet; thanks to project Gutenberg. Are the authors scared that theirs books will be illegally copied?
