"The alternative is Google, who doesn't release any top-tier paid apps on Android or Chrome Web Store."
Google's business model isn't to release paid apps on their stores. They have many free apps that are downloaded by the 50's of millions and have 4.5-5 stars almost across the board so, yes, they do release top tier apps.
Compare Google Navigation on Android, to TomTom on iOS. Navigation is free, works perfectly, and even goes so far as to include a "Car Mode" for docking your phone in your car.
TomTom costs, at last check, $95NZD. I've not bothered trying it.
I think the difference would be that TomTom supplies it's own maps in the App, whereas Google Navigation probably downloads the tiles/street view as you go.
This can make a world of difference when travelling abroad when you can't be bothered getting a local data plan.
I definitely use GPS navigation more often when travelling than when in my home country.
Google Maps for Android comes to mind. I guess "top tier" on a mobile phone is still in the tens of dollars right now, but I haven't seen an alternative (free or paid) that comes close.
Mail and calendars are also better than anything I've found in the market...but that's maybe just my preference.
That's a bit disingenuous. The fact that Google's offerings are both good and free significantly reduces the likelihood of their being expensive alternatives. It's a self-fulfilling prophecy.
There are companies that sell software that competes with things like Google Docs, Navigation, and other services. And yes, you can always point to things they do differently, but that's guaranteed. No one is going to pay $50 for something that exactly duplicates a free service that has more name recognition, so you by definition have to do something to differentiate yourself.
