After reading so much I couldn't resist to write a comment. Please don't take this as an offense anyone it is strictly my opinion.
I'm so tired of reading comments, " oh no removable battery, no sd card I'm going to LG" or something along those lines. It is a matter of time until LG does away with those things. Honestly most of you are hypocrites, first you complained Samsung has cheap design, once they make a good one, all of you complain no removable back no sd. What do you want? Make up your mind? You cant have all at the same time. Want removable back? Like your phone to be nice and squeaky? Go and buy some Chinese knock-off phone and be happy. Surely there will be plenty of people who will prefer design (Apple and many others get away with it).
I much rather carry a power bank (plus wireless charger at work) because it's dirt cheap now, than 2 batteries and a wall charger for them, fiddle around with the back, which will waken with time of constantly opening and closing it. Its 2015 not 2008.
Now for SD cards, I much rather have 64 GB or more internal memory than 32 GB + SD. Internal memory is always going to be faster, even Google steers away from it saying it slows down interface. Most of the apps can't be transferred to SD card now, even if they could be or big chunky videos take some time to load if you have a lot of them.
Last time I used SD card was in S2 and it died on me, completely, nothing would even read it. All the videos and photos I had gone forever. At the moment I use Nokia 930 32 GB and HTC One 32 GB and I'm totally fine with it as it is. I sync all my stuff when I get home.
Samsung pleased you many many times already, let them for once do something different something they want and others wont. Removable back means no wireless charging, if that is the case it is a NO go for me straight away and I have to go for S6 Edge then. However I really want a note, everything seemed fine up until now. Also SD card means they won't implement new faster memory controller (as Samsung said before it is not compatible).
