Recently I thought that I am eventually going to have to move on with the "new faze" in terms of reading, even as someone resistant to the change and who much prefers "real" books albeit more expensive. There are a number of what seem to be informally called eReaders from a multitude of brands, most of which are competing with the Kindle brand.
How exactly do they function? Can they handle pdfs and is there any specific format that they use? It is possible to download ebooks for free which would be compatible with any brand of eReader?
