My Experience so far
Pros:
1. So ordered my S8 + day before launch, got it delivered the next day in an impressive box. Imagine that getting a device on launch day without waiting weeks or months....
2. Design: first time ever the IPhone equivalent feels old and dated. Yup holding both in hand, apple has been out innovated in the design front.
3. Screen : zero redness to it, seriously....damn.
4. The OS: I own a note 4, Samsung iron man and Samsung batman, so s6 and S7 and on the S8, the OS is very impressive and polished. First time I can say it's close to matching my iPhone experience .
5. Iris scanner. Never used it, though it works...works well, I have not used the finger scanner yet....
6. Android: man..... to summarise the situation, I can run kodi on this thing... so much potential, if you are a power user, this thing will offer functionality the iPhone cannot .
7. Intergration with home and Alexa
Cons
1. Samsungcare, or what ever it's called. I added it to the basket when ordering , it was £99 .......which I though was good value, it was not till I paid attention , it's 12 months. Nope gonna cancel , and unlike apple it's disjointed. I got the cover email from the 3rd party and not Samsung.
2. See 1. Support and serivce, nothing beats apple.
3. So much apple gear.....so deep in the ecosystem....this like me, will take time to get out , though cause apple has been screwing up or neglecting its devices so much, I've already replaced my Apple TV with an nvidia shield and Mac mini with a skull canyon/core....and I can say that getting out slowly has its benefits...apple hardware is stagnating...though not easy people, a closed ecosystem for many is still the way to go
4. Apple Pay : have not setup the android pay etc, though I'd like to point out, Apple Pay in my opinion is far superior.
5. Touchid : still the best way to unlock a phone from the front, and best user experience
Undecided
Battery : this week going to test against my 6S plus: though since going iOS 10, apple has managed to screw a perfectly fine phone with OS updates . Even had the phone repelaced by apple, for the brand new one to also have very poor battery life. I remember getting my 6S plus and being impressed by the awesome battery life, now it feels like a regular iPhone, can't get me through the day
OS updates : apple is fast and Samsung is slow. Both can Improve or screw you phone. I've not spent enough time with android as a daily driver to know or from thier end. As an iPhone user , some really bad experiences of planned obsolescence where some OS updates should not have been released or at least give the user the ability to roll back a version.
Security / privacy : would not trust either one with my data, though the iPhone is a better device from that perspective , as a hardware unit. iCloud backups....another matter.
My world is better than yours : fundamentally neither platform form is perfect, if you can find a balance between the two, and PCs you will be in a good place. If you can honestly say that one platform, say apple is superior to all others in all repects, put down the koolaid, this is a personal experience issue, you judge your own marker, and this is somethig I need to decide on. Being a massive Jobs fan, had he still been around, I'd be investing towards apple, with Tim playing the politician and raising prices each year, I feel I'm slowly getting pushed out....the new iPhone will cost me over a thousand pounds, probably about one thousand two hundred with AppleCare ....I really think smartphones are going the wrong way and frankly no phone is worth more that a thousand .
Keep or return . I have a month to decide if I will keep the Samsung, will see, I will admit that it will not be easy to leave the iPhone, it's a part of life, though this is the most polished and android device ever. Will see.
