Hi JinRoh, The Sony is said to have a bookmark function that is easier to use but since I never use bookmarks, it is not an issue. It also reads DRMed e-books in the EPUB format which you can buy from Waterstones in the UK, but it doesn't support the Mobi format which I am interested in.
For a fair comparison, look at this site:
