Pros: produces the best hardware & owns the richest & most well-composed app ecosystem both for iphone and OS X. When you go with Retina Display on the MacbookPro or the new iMac 5k everything else looks just inferior. Reading text on them is just how it was always supposed to be.
Cons: Expensive. As you said restrictive. You do need fast internet also (but i think thats just a con in the case of Lebanon lol ). Most importantly apple is a money whore. After about 2/ max 3 iOS updates your Iphone becomes a piece of junk. Same goes to Macbooks, OS X Yosemite is rated like 2.5 stars in App store because is killed so much Macbooks. Apple does that purposely so you keep buying their overly expensive devices. Also although they have the best app ecosystem, there are spicy prices for these apps. Everything has its cost. I think the windows taskbar is much better than the dock, while multiple desktops and gestures are awesome.
Microsoft is currently just a mess though I love it the most. Windows 7 was the peak, windows 8 & 8.1 were a fail, then 2 years of nothing and now we’re waiting forever for windows 10 to be released. When it comes to phones, they just started recently. While with the iPhone you get to throw it after 2/3 updates, with the Lumia in actually gets faster and you get extra features like with Lumia 930,1520 & 800 ppl got 4k recording after the updates LOL . Also when it comes to imaging they are the BEST but the platform is unbearable. Ive had the lumia 1020 sin 1.6 years and its still the killer camera phone till now. And although for me the camera is the most imp. thing in the phone, i cant bear the platform anymore their updates take for ever, Lumia denim was announced 7 month ago and so many phones didnt get it yet. Also Microsoft hasnt released a real flagship phone since the 1020 which is why the currently suck. Although that I believe Microsoft is the most ethical company, they produced internet ready phones for 29$ & 110$ which gives accessibility to technology for the largest amount of ppl. Bill gates will probably be announced as the person with the most positive impact on our plant after he dies.
HTC : The one M9 is my next phone until microsoft releases a new flagship with windows 10 for phones. Its kind of a middle ground 2nd best platform, its going to be blazing fast, a 20 megapixel rumored cam ( fingers crossed lol ), the Boom sound is something unique to them, its helpful if you’re a deep sleeper in the morning.
Samsung : meh
Again the camera for me is the most imp. feature to certain degree after a bearable platform, you dont need iOS because because at home or the office u have you’re laptop/ipad to do your work, doing your work form a mobile is never going to that productive no matter how good the software gets. On the other hand “Mobile” means going out & capturing the moment with a good cam.
