24 hours with the 6+
1. Is it big? Oh yeah.
2. Is it sometime awkward to pick up/hold securely? Yes
3. Is it heavy? Noticeably heavier than my previous 5, but by no means too heavy.
4. Is it pocketable? Jeans, yes. Coat breast pocket, no.
5. Is the screen as good as the reviews are suggesting? No, its better.
6. Have i got used to it in 24 hours? Yes, completely.
7. Is the battery as good as expected? Yes, not charged it since i got it 24 hours ago (fully charged). Still got 20%.
8. Can it be used with one hand? For me, yes.
9. Do I regret choosing it over the 6? Not one bit.
10. Do i still need my iPad Air? Nope. Not touched it in the last 24 hours.
11. Is it the best phone Apple have ever made? Undoubtedly, by a significant margin.
For me, the plus turned out to be the best option. I was undecided before and after the pre-order. I hardly make any calls, don't travel much and use my phone far more for web, email, gaming etc...which pushed me towards choosing the plus. If calls & portability are your primary needs then definitely go for the 6 as the plus can be a pain to carry around. I've had to tighten my belt to stop it weighing down my fat-ass jeans too much

If you want to stop switching between iPhone, iPad & Mac then get the 6+ - it really does work well as a single device for my needs.
