I just recent
I've been using a Note8 for work for the last 2 weeks. I also have an iPhone 8+ for personal use. I find that I love holding the Note8 because it a a beautiful piece of technology. But I also have multiple iOS devices, so if I need to make sure I can access something quickly, I make sure to use my iPhone.
As far as work is concerned, I've had trouble getting accustomed to not having anything like iCloud for Windows for the Note8. Contacts and calendars from Outlook no longer sync as they used to. I've been trying to migrate everything to a Google account (someone suggested that on these forums), and that has been OK at best. I'm sure there are other, better options, but I have yet to find them.
TLDR; The Note8 is pretty and sleek and I could stare at it for hours but iOS is tough to live without for me.
Also, I didn't think I would use the S Pen as much as I do, but it is one of my favorite things about the Note8.
Keep in mind I haven't really delved deep into the Note8. I'm sure the more I use it, the more I'll be able to find new ways to replace iOS features I've grown accustomed to over the last 10 years.
