There are a few things about the Sony PRS - 650 that could use improving, mainly the same things that are listed on the PRS - 350 review: the lack of styling options, such as changing line - spacing, margins,
font type, etc, all of which requires adding
fonts and editing the
CSS file of an ebook to change styling; the fact that landscape mode breaks pages into two sections for ebooks, showing duplicate sentences; and other minor annoyances like having to go through multiple menu
selections for certain features and settings.
