This might not be the right forum, but as I can't find enough info elsewhere, I'd like to ask in this community. I'm seriously considering getting an ereader for reading only (not a tablet). I can get a Kindle on amazon.com, whereas Nook cannot be bought online (for my location). However, I can get either of them in London's bookstores (Waterstones, or John Lewis) where I'll be next month.
My main question here is, since these two readers differ in ebook format (kindle or ePub), and I have a feeling that ePub might be more common, is this right? Are ePub books more common? I have an issue with amazon, as I can order only from .com, but not any other (such as co.uk), whereas I think I can order online from other sites (Waterstones, ebooks, Barnes & Noble).
Are there any Kindle/Nook users here to share their experiences with readers and buying different ebook formats?
