I got to play today for around 45 mins! The back was a little disappointing( ok maybe a little more then a little). Its not even plether like, its just straight plastic(it looks cheap). The stitching on the white version looks like poo(it looks cheap). I didnt get to see a black one. Its EXTREMELY light. Almost too light, it throws you off a little. The fuax metal border didnt inspire confidence. I think the neo hybrid case would make a good bed fellow.
Ok now that i got the bad first impression about the build out of the way. The metal border did allow for more grip due to it being ribbed. The back is grippier vs the note 2(it also feel better in the hand vs the note 2, smaller somehow). The S pen allows you to put it away in 2 different ways, so that makes it more functional. The S pen was very responsive, you could strictly only use the S pens and be just fine. The S pen feels better in the hand vs the note 2. I opened up dev options and turned off all ani and enabled force GPU, like I always do with every 4.0+ device and its definitely a responsive device in every way. Its sadly better then my nexus 7 V2 in every way possible(besides build). Everything is very fluid. The screen looks GREAT! The camera is pretty cool, the burst option will be fun with my dog. I couldnt find the video settings to change from 30p to 60p (or 24p if its offered). You can take full size pics while recording which is cool. The editor is nothing to brag about really. Its an extremely functional gadget. I dont know about call quality or DB or anything. The speakers sounded good while playing what does the fox say on you tube, the music video was cool to watch on that huge screen in HD. It felt just as fluid as my Iphone 5(I had 8 windows open multi tasking and didnt stutter what so ever). Compared to the current note 10.1, it blows it out of the water in every single way!
BTW Im left handed and have REALLY bad handwriting and it recognized it just fine(this was the most important thing to me! The only real test I had for it), also you are able to write pretty dang small and it still recognizes it!!
All in all, I signed up to hold a device for instore pick up on the 2nd! The first impression didnt inspire confidence, but its nothing a decent slim case wouldnt fix(and cover up the stupid back IMO)
