Sure is nice that I can sign business documents on my Note 8. Couldn't do that well on other devices.
You can do it on other smartphones, but it's nowhere near as precise as with the SPen. I've done my signature in a document on my S7 Edge and on my iPad Air 2, and each time I wished the Note7 had not gone up in flames and missed my Note 4.
Also for Annotating documents, Images, as well as grabbing content from areas where the standard Android Copy feature does not allow you, the SPen really takes things a step forward.
I had a brief I had to edit while out of the office, it required me to get the Instagram names of a number of Instagram Influencers, now with a standard Android (S7 Edge, S8+, LG V20, LG V30, HTC U11, Pixel XL etc etc..) you have to take the extra step of getting the whole Profile URL, yet when I had to do that with my old Note 4, I just pulled out the SPen and held down its button and copied the Instagram Handle, no having to mess around with URLs.
Another example is when wanting to take words from an image either from the internet or a pic you've taken, with Standard Android phones you'd have to try memorise it, but with a Galaxy Note you once again pull that SPen out, highlight the text that you want from the image and the phone copies it as normal text. Where does this come in handy for me?
-Grocery shopping, my housekeeper sends me an image of the list and with the Note I'd convert it to text in no time.
-Ingredients off a package label (when the girl you are seeing is a health freak, trust me this comes in handy
)
-Business cards ,we are in the digital age yet people still carry these things, very odd,but the Note 4 helped me a lot here.
The SPen generally just makes a lot of things easier to do in terms of grabbing and manipulating content, it takes out 2-3steps that I'd have to frustratingly have to go through with a standard Android, well for ME that is. As much as I have loved my S7 Edge with its great battery life, and compact design, man have I missed that SPen. Almost everyday I run into something where I am like "the SPen would make this a lot easier to do".
The SPen and Note are generally not for everyone and that is why I say, rather compare the V30 to S8+, as if you have no use for the SPen, the extra 2GB RAM, Dual OIS Cameras and SPen Suite, then you'd be wasting money on the Note8.
