I just bought the Note 4. I appreciate the removable back. Not that I need to change out batteries very often, but on a trip... at least I have the option. Yes, like most of us I put a protective cover on the back of my phone, so I have to remove both the cover, then the back of the phone to get at the battery and/or memory card. Glad then that I don't need to do this very often, right?!! But what impressed me the most (on the Note 4) was the cost savings on the SD memory, because I get to install that myself. If I had to decide between a 32GB, 64GB, or 128GB fixed amount of memory (in a Note 5 purchase) I would have paid about $100 for each 32GB increment (so $300 to get to 128GB). I bought my Note 4 (with the standard 32GB internal storage) and then online I purchased a quality (level 10) 128GB micro SD for only $75. That's a big savings right there. Also, Samsung is giving a $200 rebate (during July/August 2015) if you paid full amount for the phone. So all-said-and-done I'm getting a Note 4 w/ 32GB+128GB for about $600 (you have to figure in taxes). Down-side thoughts on my Note 4 purchase - soon my provider will stop upgrading my OS for me and, I'll have to do that myself (oh well, it happens with them all eventually). Then of course... if you really want the newest thing... Note 5. I'm sure you will enjoy the new stylish look, USB C, bigger battery, improved sound?...
