Thank you all for your input so far.
True, I haven't said how big, but 8" is the upper limit as I will mainly use it for reading literature.
Highlighting is insofar important as I use it to extract key paragraphs to my PC and into a seperate document; not because I use my reader for note-taking. The 10" readers are a bit overkill for me
Hm, so its boiling down to personal taste, it seems.
Oasis has better highlighting (although there is no Mac version of kindle mate) and possibly nicer screen size for reading.
Aura 1 has Pocket, reading stats, yellow light but no landscape.
Hard!
