Short version: for me, Android just does more for my work flow than iPhones - and actually implements surprisingly well with Macs, plus it complements iPads very well....same thing that got me hooked on OS X, got me hooked on Android...work flow.
You still get your iOS "fix" from iPads, your FaceTime, iMessages etc... I find having an iPhone and an iPad to be a wee bit redundant, its literally the same thing just on a bigger or smaller screen; with either multitasking or phone functions (which can also be a huge plus depending who you ask)
(very) Long version if you're interested in reading it:
I still have windows on my macbook, (windows 10 actually runs slightly faster on the macbook than macOS but both run fine), still have an iPhone as a secondary device, and tried out many other tablets/combos from Nexus 9 to Surface Pro 3
For me, as far as tablets go, the iPad is the best tablet experience. You get a fully fleshed out iOS experience (multitasking et al) and an excellent pencil (I have a mini 4 right now but will move on to the new iPad this year so I can jump on board....it is very awesome for learning what many of my classes require) which completes a lot of what I need in a thin portable form factor like a tablet. Plus, what purpose does it serve having iOS on two devices, one being bigger than the other? These aren't the days of 3.5" displays anymore, the larger screens on modern iPhones negate a lot of that glistering attraction.
As far as computers go, I was a windows guy since Windows 98...Windows Vista is what turned me off Windows. I thought it was terrible, buggy, laggy...you name it. Debated jumping to Mac at that time as I had used macs in grade school and had no ill feelings towards them, but the prices I couldn't justify at the time. Just too much money. I was only in high school at the time and had to be careful with my budget.
Plus, Windows 7 won me back - I loved windows 7 and all was well until Windows 8 came out and I just couldn't "like" it. For me the main reason was it disrupted all my work flow significantly. I had just started university so I needed something with proper work flow. I tried my best to like it, I really did - I gave it several chances including when 8.1 came out, but it just didn't work. It just didn't "click" with me.
This was when I gave OS X a go, in 2011 with Lion. At this point I had already had my first iPhone (and iPhone 4) so I was quite positive about giving Apple a go, I had money saved up and I could afford a Mac computer. I was also looking for my first laptop instead of a desktop, so the Macbook was high on my list.
...and wow did OS X blow me away...I know Lion isn't held in the greatest regard but the work flow was unlike anything I had experienced.
Multiple desktops and gestures was beautiful to me and it helped so much with everything. I was gliding through research papers, easily connecting my iPhone to the computer, I had tons of ports and space on the Macbook Pro that I ended up purchasing, I could upgrade it....it was the gift that kept on giving.
I was not, and am not a gamer on computers so that advantage of Windows PC's never attracted me. I was just "used" to Windows and knew the ins and outs so thats why I loved it.
However, using multiple desktops and gestures blew my mind and that was what convinced me OS X was for me: the user experience. It was a learning curve for me, but a small one, and I fell in love.
Plus, you could bootcamp which was awesome. I am currently not a fan of where Apple is going with their current MacBooks with the inflated prices, especially in Canada, so I am a bit turned off...(though I watched this happen as a non-OS X user at the time of the Macbook Air's release when it first came out so I am looking forward to future iterations)...
...and my current MacBooks work fine so its not a big deal. I use my old MBP as my main "desktop" (w external monitor and large 4TB external drive) and my retina Macbook as my portable unit, something I got a fantastic deal on because my cousin works at the Apple store, that I lug around to and from school.
It suffices, I require a computer for school anyways so it works out. I have Windows 10 on it as well - for me again this was a big selling point, that we can use 2 operating systems on one computer and seamlessly too. Windows 10 is my favourite version of Windows since 7, I love the dark theme it has and it runs beautifully on the retina Macbook. Seriously sometimes I wonder if the macbook was designed for Windows 10 or OS X!
So although I'm a fan of Windows, I'm an even bigger fan of MacOS
Now....as far as phones go...I was a staunch iPhone user since the iPhone 4 won me over. I loved transferring my data from the old phone to the new phone, seamlessly. At the time I became a dedicated iPhone user, Apple had - easily - the best camera in a phone, by FAR the best build quality, and the fastest operating system with enough features to satisfy my needs.
But 2017 is not 2011. Today, modern high end Android phones offer beautiful hardware often times with more features than their iPhone counterparts. It is subjective, but for example the Galaxy S7 offered just enough to win me over the iPhone 6s, and then when I purchased an iPhone 7 it actually felt like "downgrading" despite being half a year newer.
That moment, that "this feels like a downgrade" was when I realized Android had become more useful to me. I had tried many times to go android just to test it out. I went with low quality options vs the iPhone (Moto G), higher quality (One Plus) and Top of the Line (Nexus 6P, Galaxy S6) but none were quite enough to win me over. Though the S6 came close.
But when the Galaxy S7 came out, I had a chance to get one for free on contract at launch from my carrier so I decided to do it. The iPhone 6s prior to this was my favourite phone ever. But i gave it to my mother who needed a new phone. I decided to take on the S7 full on and give it at least a month before I decided to switch back to iOS.
But that switch never came. Little things about it kept impressing me. I know it didn't run stock Android but it didn't matter. I was very impressed with the OLED display and the resolution was immediately noticeable. I appreciated the water resistance which came in handy during trips to the mountains or lake. I loved the battery life, which after some customization blew away anything I had experienced with my iPhone (which required daily charging)...heck I loved fast changing too...and apparently the S7 didn't even have top of the line fast charging compared to other phones.
Always on Display turned out to be a trojan horse, but it was really the whole package....it did so much, it had an exceptional camera (with very fast focusing), I could upgrade the storage when I needed, I could customize it significantly more than the iPhone....it basically had so many features that I didn't know I wanted. Even that little LED light that I always thought was annoying turned out to be excellent.
And oh, the back button. Sure you can swipe back on iOS (which I also like a lot) but the back button works wonderfully when you get used to it...I still reach for it on my iPhone.
Then the 7 came out, and I couldn't come back the same way I couldn't go back to Windows. Yes it was fast, yes it was a welcomed return to an operating system I enjoyed, and iOS 10 was the best iOS experience yet....but it just didn't compare to what I could with Android.
Android runs smooth and fast enough, it has terrific build quality (the S7 reminds me of the iPhone 4 with its glass on glass with an Aluminum 7000 series metal band around it), it has a fantastic camera that loads faster, focuses faster, and is identical to my iPhone 7 in terms of overall picture quality, no problems with the finger print reader (though its not quite as perfect as the iPhones...but it works)...and the screen....iPhone 7 might have the best display yet in an iPhone, with a rich colour scale and fantastic warm colours but it *does not* compare to the S7's screen. It is night and day. OLED offers true blacks and the resolution is so crisp. You can notice the most it when watching videos, which I do one the plane often (my iPad is a 16GB machine unfortunately and is already packed with my school focused apps)
The one knock against the Galaxy (and this is a big one) is the speakers are crap compared to the iPhone 7...iPhone 7 speakers might be some of the best I've heard in a smartphone to date. The S7's are even worse than the S6's, which I used to have so I could compare them well. That said, it does have a headphone jack which I can use some very expensive headphones I invested in without issue and it sounds very nice (while charging it if I need! without getting a dongle or using an adapter...sorry iPhone 7, function over design here). Wired > Bluetooth, even though I got a nice pair of high-end wireless beats headphones that sound great...but bluetooth has a ways to go still.
It was the exact same feeling I had when I went from Windows to Mac OS, that i got from iOS to Android....it simply enhanced my work flow. The widgets was by far the biggest one for me, specifically Google Calendar which syncs my busy schedule with ease....and there are a few medical apps that while great on iOS, I can instantly access them from the widgets which I need for school.
The dark theme I use plus a black background gives me twice the battery life I get from my iPhone 7. And there is a super handy Ultra Power save mode that extends my Galaxy's life if I need.
So now its all about work flow...and I find that my workflow is most enhanced with an Android Phone, an Apple Computer, and an iPad.
Phew - Congratualtions to anyone who read that gigantic essay!! (why tho?) Hope it was entertaining to someone out there lol
