In our latest issue (Sept 2012) of Le Journal du Barreau du Québec, page 36, one can find
a fairly sweeping statement to the effect that free email services like gmail are not recommended with regards to confidential emails.
For example, I'm seeing a
fairly consistent behavior when tapping the «nook» button twice after turning a page: the last line on the screen (the one temporarily «obscured» by the navigation panel) looks noticeably darker / clearer than the lines above it (I want to say it is «as clear as can be» but that might be a little too
sweeping a
statement to make at this point).
