rgeorg - I might have missed it but have you considered the Galaxy tab pro lineup, basically the same performance as the S tablets with some minor differences (IPS display, 2gb of ram, Qualcomm SOC), since the S came out the pro has received a few discounts but if you like Amoled when you see if go for that, specially if you read books using a black background with white text. Also take a really hard look at the 8.4 models I find them to be the perfect size for a tablet, see if its something that might work for you if not by all means go for the 10 inch one
If you have any questions about the 8.4 Galaxy tab pro i'd be happy to answer or I'd have to get home and see if it has a night reading mode like the note.
HarryT - bobstro - You probably know this already and have not done so because of different reasons (security, warranty, you plain old don't want/like to do it) but I just wanted to point out with root and an app in the play store you can get back the capability to write to an SD card on 4.4
