Despite its good looks and solid build, however, the Sony Reader’s usefulness is limited by the absence of a proprietary bookstore outside the USA and Canada. Although Sony has partnerships with major retailers in some countries (for example Waterstones in the UK), this is by no means the case elsewhere, so if you want a reader that offers downloads of the latest bestseller, this is not the place to be. If, on the other hand, you already have a number of ePUBs, PDFs and other documents, you will find that uploading them is a painless process.
