I ended up ordering the Note 10 in the Skittles color last night; I had "reserved" a phone before the announcement. I would have liked the Blue but I'll have to settle for the Blue leather case (that I got using the instant credit).
I seriously thought about the Plus but didn't want to pay the extra $150 -- I can't see myself needing more than 256GB storage over the next two years (if I even keep the phone that long), so the SD card doesn't mean much; 8GB of RAM is plenty for what I do (most phones still have no more than 4GB). The larger battery would have been nice but I don't have to have it, chances are the smaller battery will still last a full day for me; and I'd likely keep the Plus in the "default 1080P" mode to save battery -- so not even that much difference in the screen. Beyond that, the Note 10+ is tall enough that it seems like it would not fit comfortably in my pants pocket, instead it looks like the top would stick out. So, I decides to save the extra money, the regular Note should be great for me.
