I haven't had much time to really pay with it yet, but I noticed that blocking mode is gone like my N2. There is a little bit of bloat, but not too bad. 
I agree on the 16gb.  I have a 32gb sd card installed for music and the like.  I have chosen not to install a lot of big games to help keep the available storage in check. I will mainly be using it for note taking, web browsing, calendar and watching movies.
I am giving up my 3rd gen ipad with VZ LTE because I really like the Note experience. I got really bored with ios. 
I will try and report back with any differences I encounter compared to the wifi model.
