From least to most important:
5. Facebook: I gave up on Facebook several months ago, I don't use WhatsApp and barely touch Instagram. The only service of theirs I use is Messenger and even that is hanging on by a thread, with only a few friends I use it to talk with. Opinion of company: Low.
4. Apple: Apple is not my first choice for devices or services. While I do have a handful of Apple devices, they barely get use and my life would hardly be impacted by abandoning them. My only interest in Apple would be as a platform to develop for, considering its large install base. Opinion of company: Medium.
3. Amazon: Because I do not live in the US, shipping from Amazon is way too expensive for my taste, so Amazon is a last resort. I usually get my products from my local online megastore, and if that fails, I usually choose Ebay before Amazon. If shipping to my country was free or comparable to local shipping, I'd be tempted to put this at #2. Opinion of company: High. (I'm sure they're evil like every other big company, though.)
2. Google: I don't use Gmail. I would be fine using Bing. I am contemplating getting an Android phone, but only because iPhone 7 was disappointing and Windows Mobile is dead. And Google+? LOL! Only reason Google is so high is because I can imagine abandoning all products and services from Facebook, Apple and Amazon before I abandoned YouTube. (I am not loyal to the YouTube brand; there's just no decent YouTube competitor. If one appears, I will be more than happy to jump ship.) Opinion of company: Medium.
1. Microsoft: I use Windows for my OS, Outlook for my email, OneDrive for my cloud storage, Xbox for my console gaming, Visual Studio for my programming, and if I were rich enough I'd have a Surface Book and a Surface Laptop. And, while none of these are perfect, I am perfectly fine with these products and services. The only Microsoft product I use and will be abandoning is my Windows phone. Opinion of company: Medium-High. (I enjoy their products, but when they don't have competition, they tend to suck. It just so happens to be a point in time when they have a lot of competition.)
