I've been heavily using Apple products for much of the last 10 years, but over the last few years I found that my needs and the direction of Apple diverged. I believe this has a lot to do with Apple's current leadership, but that is just my opinion. The bottom line is that I discovered that its dangerous to be to "all in" with one company to the point of being trapped and at their mercy for your tech future. I got more and more unhappy with each keynote, and each trip to the Apple Store, and during 2017 finally did something about it. At the beginning of 2017 my MacRumors signature was all Apple... a year later its almost all not Apple.
Router - I have used Airport routers for years, and always had good luck. Over the last several years with no updates and the world advancing without Apple, I found that more and more my iDevices were not switching from one Airport to the other and I was getting crap wireless even though I recently had put in gigabit fiber to our house. This prompted me to do testing and discover how bad things were. I ended up replacing the Airports with a Netgear Orbi, and was also able to eliminate a MoCA backbone network due to the fast backhaul wireless on the Orbi. I now get very fast an reliable WiFi in the house and even in most of my yard.
Computer - About 5 years ago my job change took me from using a MacBook Air as my daily driver to having work on Microsoft's platform and home / small biz on a Mac. The MacBook Air got passed down to my daughter and I maxed out a Mac Mini with a Thunderbolt Display on one side of my desk, and my Dell laptop was tied to a similar display on the other side. This worked OK for a while, but when I finally got to Windows 10, and saw that Apple had abandoned my two favorite machines - MacBook Air and Mac Mini, I decided to explore converging. I had always believed touch on a laptop was dumb, but I more and more was intrigued with using a pen for notes in OneNote. Midway through 2017 I jumped in with both feet and got the new Surface Pro to replace my Mac Mini and Dell laptop. The Mac Mini was retired to just backing up my wife's iPhone and iPad. I've really liked the Surface Pro... pen based notes, and a very compact package for travel. My travel backpack weight was cut by about half.
Phone and Watch - My last iPhone was a 6S+ and also an Apple Watch S0 that I used together for 2 years. I waited to see what was to be the iPhone X and wasn't happy with what was announced... no plus size, no FPS, and that notch... and also the headphone jack which caused me to not upgrade the 6S+. Alternatively, there was the 8+, but boring to me as it didn't much new for that much money. I decided to give the Note 8 a try, having only ever tried Android once before (Galaxy S5) and I really hated it. I gave it 6 months and was truly miserable. But with good deals from AT&T on the Note 8 and Gear S3, I decided I had nothing to lose to try it. Other than a little messaging friction with my all iOS family members, I have loved the Note 8, and especially the Gear S3. I was shocked actually that I liked the S3 better than Apple Watch.
Music - With the Gear S3, brought the problem of Apple Music not working with it. A switch to Spotify Family solved this problem and I've found that for discovery and interoperability with all my devices it works great.
Car - Now both of our cars have Car Play and Android Auto. I suppose they both give about the same service, but my wife and I can coexist ... she with iOS and me with Android. But any time there is traffic, Waze is the only way to roll. We both use Spotify for music, so that is roughly the same.
Home Automation - From Black Friday through New Years, I've jumped into home automation with Amazon Echo, Philips Hues, Smart Things Hub, GE Z-wave switches, TPLink Kasa outlets, Nest Protect fire alarms, and we already had a Ring doorbell and stick up camera. What I found so far is interoperability is really important. All that I have I can use on iOS or Android. Had I gone down the path with HomeKit, I'd be locked in.
TV - And over the last week the final piece to the puzzle came into place. I still had an Apple TV latest generation on our main Family Room TV and used an old Harmony One remote. After getting some more Amazon Echos and enjoying multi-room music with Spotify, I bought a Harmony Hub and Elite to replace the One. I experimented with Chromecast, FireTV, Roku, and Apple TV. With Apple TV, the only thing I could control from Echo was just turning it on and off. FireTV was nice, but way to "biased" to Amazon content. The closest to the Apple TV unified search was Roku, and its the more mature of the alternatives. So now the Apple TV is retired until we get a newer TV with an extra HDMI port. We have 3 Rokus, and when on sale again will also had ChromeCasts to each TV as well.
So here's the deal. Nothing wrong with someone wanting to do all of this with just Apple stuff. If you want to go all in on Apple, I'm not going to tell you that you are wrong. But, if you go too far into some of these areas, you are literally locked. A heavy investment into HomeKit automation, or Movie/TV content, and it would very difficult to move. I'm now investing more in open and interoperable stuff. The rest of my family uses iPhones and iPads. For computers, one has a Mac, one has a Chromebook, and one has Windows. We are all so far getting along OK and I think they realize I'm not changing back any time soon.
Hopefully this thread doesn't digress into a bashing and flaming thread like so many, with a few Apple fans trying to take the discussion off on futile tangents. I posted this to share my experience with this transition, to provide info for anyone else considering it, and to hear from others that have done similar.
