That makes me feel like a simpleton though that can't make up his own mind.
I'm justtrying to think longterm here. Whatever I choose will dictate everything else I buy like tablets, streaming boxes, laptops, and etc.
Justification for the long term is really the last thing you need to do.
While Apple's continuity features are going to be nice, how much are you really going to utilize them? Same for Windows unification scheme?
If you actually need these features then by all means go for it, but if you really don't why invest in a very expensive ecosystem for something that is not necessarily the best phone for you or in a ecosystem that isn't ready?
I fully understand the lure to both, but neither offer a phone that gives you the options that a high-end Android phone has.
Only you can decide what you use your phone for and what you need.
I utilize all of the platforms and choose what works best for my needs. I don't need a desktop computer for a cell phone, even though that would be a nice feature, nor do I need a fully integrated house that's integrated into my mobile devices. Not yet at least. I have seen friends going all out with this but I am not really ready to commit to doing so.
Android phones and tablets work very well and have all of what I need and surprisingly they work well with my imac too.
I use my phone far more than anything else, so it is the most important part of my computing needs. I have gotten bye with a iPhone and also a Windows phone but neither can give me what I need in a cellphone. I hate to just get bye with anything... and much prefer to have what I truly like.
Androids IMHO have gotten a bad rap on several occasions and most often needlessly since there are so many alternative phones to choose from. They are just as secure as the other platforms just as long as you know what steps to take to keep them that way. Androids actually get as many updates as ios or WP and has new apps all the time . Androids have the best selection of phones to choose from from small easy to carry to the largest phablet types, and are the most customizable devices you can buy.
Only you can decide as I said on just how important these features are to you and what you think you need.
Make a list of of the reasons and start comparing each to find the best for you.
I will only caution you to see what is fact and what is unfulfilled promises or hype before investing heavily in any platform.
