Re: Will you upgrade to Note 5 if it doesn't have SD slot?
At the end of the day, people's decision about SD Card v. Cloud is subjective, and people will go for what is more convenient or appealing to them. However, this is my opinion on it:
I think a lot of people are making the mistake of thinking that without the SD Card, they will not be able to listen to music or record videos efficiently. Which is totally not true. Your phone still has local storage, which you would be able to record video, take pictures, or do anything else you could with an SD Card. The cloud is not and should not replace local storage. The cloud I believe should be more so a place to backup your documents and other files. The only benefit I see with using an SD card is the transfer of it from device to device. Other than that, nothing has really changed.
For those that make the argument about burning data or having no coverage, those are the people that are using the cloud wrong. The cloud is not replacing your local storage, and you do not have to backup your files to the cloud every 5 minutes. I personally have my setting so that it only backs up when I am on wifi, and will pause when I am not on wifi. This has worked pretty well for me, and when I check my data, my cloud transfer doesn't even show up as something that is wasting my data. It honestly does not take long to back up files to the cloud on a decent connection. You do not need a fiber optic connection to make use of the cloud.
For those that make the argument of phone storage, I believe this is not much of a strong argument as well. I currently have the 16GB version of the Galaxy S6 and I to take a lot of pictures and record video. I still have a good amount of free space left on my phone. I record in 720p video. What I do is backup all my pictures and videos to the cloud, and if I do not need them, on my phone, I can delete them, but also knowing I have them saved. On the contrary, if you do listen to a lot of music, this may be a problem, as it was for me. I do like to keep a lot of music on my phone locally, and I do not do so on my S6 because I prefer to save the phone space for apps and other things. I use the Asus Zenfone 2 as my music player, which does have an SD Card. This alternative has not been a problem for me so far, and I actually like carrying 2 phones around.
Now I highly doubt the SD card was the success or the optimal feature of the Note series, and everything you could do on the Note 4 I'm sure can certainly be done on the Note 5 if not more. I know personally I probably will not use the stylus on the Note 5. I will use it more so like I do the S6. My main reason for transferring from the S6 to the Note 5 is the 4GB of ram and the bigger battery (4GB of ram makes a noticeable difference from 3GB...comparing the Zenfone 2's 4GB to the S6's 3GB).
As for removable battery, fast charging has really worked well for me. Unless you are always on the move and cannot spare 5-10 minutes to fast charge your phone, then a removable battery is not much of a big problem. Now me personally, I prefer to have the option of the SD card and removable battery, but I will not tell myself I will not get a great phone because of those 2 features.
I was initially upset when the S6 was announced that there was no removable battery and SD card, especially since the SD Card was an needed feature for me. The camera is what drove me to the S6 over the need for a SD Card. I first tried cloud when I had my S5, and I can say it has been really helpful. For those that oppose it, I would say just try and make use of it and see if you would like it. Sure there are times when you won't have a connection to access it, but like I said, it should not be your main storage. Continue to keep pictures and videos on your phone's local storage, but if you do use the cloud, use it as a backup, not replacing your local storage. I also think its better to get used to it now then later because it seems like non-removable battery and no SD card is becoming the trend for mobile phones.
