It's a wonderful and beautiful device! Well, I was looking at specifically the Honor 8 versus the Zenfone 3 - they have similar specs and both intrigued me over the OnePlus - but the Honor 8 won out. Newegg had great deals on either device but I'm happy with my choice. However, it was super tough - I had to make a pro-con list!
You could definitely do what you suggested in your post - it sounds like you really want the Zoom 3, so go for it if you do! Plus, perhaps you won't like the S8 after all when it comes out (you never know, right?); so at least then you'll have a great phone already. I've heard good things about Asus - it's a reliable brand and their phone line seems to be no exception!
Good luck, and let us know what you decide!
Glad your loving your daily driver!
For sure Morty & I def appreciate the advice!
