I've had the Note8 since yesterday evening, and these are my first impressions.
I was using, until yesterday, an S7 edge. The last Note I had was the Note 3. But I have used iPhones, Windows phones, Blackberries.
With that said, coming from the S7 edge, this Note8 is feeling as top heavy as Dolly Parton on a pogo stick. I'm hoping over time I will get adjusted to the size. No problems reaching the power or volume buttons. And the one thing I am very happy about is the edge on the Note is not so dramatic like it was on the S7. I don't lock my phone (it's my precious) so I don't care about the FPS on the back, although it is a really awkward reach.
I lasted with the Samsung Experience (TouchWiz) for about 1 hour. I now have Nova, and as such, I'm a happy camper. Hated how Bixby was over the left side, and I have more control over the dock with Nova. Themed it with a dark black background, and it's not all the way to my liking yet, but will be by the weekend, after I am done pretending to work today.
The app pair in combo with the sPen is one of the best features of this smartphone. I was swapping two browsers (Chrome and Samsung browser), cutting and pasting. Switched over briefly to my kids school web site, used the sPen to note a couple of assignments he missed, jotted down some ideas for punishment (that included an old fashioned but effective flogging with a pool noodle) then went back to copying and pasting some bookmarks and such.
Make no mistake about it ... the sPen is the JAM! I am obsessed with the clicky thing on the end. I can't stop, and I need help.
I consume a lot of YouTube videos, and a lot of potato chips. This screen, therefore, is awesome for watching vids, especially when they are formatted for the 18:9 ratio. And the speaker, for all the knashing of teeth by the audio elite on here, is IMO very loud and clear.
I did not have the burning pleasure of owning the Note7. But coming from an S7 edge, this is a nice upgrade in screen size, but mostly a huge change in the way you CAN use a smartphone. It's all about the sPen.
