Wow, never expected so many replies to what was almost an off the cuff comment.
Let me clarify things a little. I was very tempted to buy the P4 on the basis of the claims made. Greater distance, battery life and all around improvement in the Phantom performance. At this point you usually get comments like "Jimmy flew his 200 miles and the battery lasts for days etc" great. I believe you. But sufficient enough members have expressed dissatisfaction about their recent purchase to give me pause for thought. Everything new has teething problems, real or imagined. If you are happy with your P4 then smashing. I am happy for you.
My P3P is working well, subject to occasional 'opps' on my part. So I will keep flying it until I outgrow it, which hopefully will be quite a while from now. Only then will I consider swapping it out for a later model.
As for complaining and not complementing you obviously do not know me, and there is no reason you should, at all. I make it a point to write and compliment companies and people for their service and products. Be that a hotel or the guy who sold me a bottle of Bilt Hamber alloy cleaner on the internet last week. I take an occasional Mars bar to the girl that looks after my horse because she puts that bit extra in and I feel she should know I appreciate it.
My philosophy is that
everyone should be as quick to thank as they are to complain. Everyone is entitled to their point of view, even if it is stupid.

And someone always knows better than you do. I am a great believer in others personal reviews of products etc. They tend to be far more frank (no pun intended) and honest than the manufacturers blurb. Hence the reason for my original comment.
I apologise if any of you feel I was attacking your pride and joy your new P4, that was not my intention. I meant what I simply said, "So glad I waited and did not buy a P4" If I had said the P4 is a heap of ******** (make up your own word) then you could complain. Just glad I no longer impulse buy with "I want one" eyes.

That was the original intent, so glad I did not buy until they have sorted out the teething problems.
