Do you read ebooks on your mobile phone?

Hi friend. That is a good idea to have some books to read while traveling. How ever a hardcopy has its own advantages. Reading text on small mobile screen is not what I enjoy. Also having the light on may finish the battery. Maybe I'm thinking like this because of considering my old mobile phone :)) Having a big screen with big fonts and appropriate light it may be considered as a replacement to the traditional way of reading. Also because you have almost no limitation in the pages and more pages will not make your luggage heavier.
