As long as one of those options is the one I want, two choices is one too many for me.
Honestly, how many freaking web browsers do you need to choose from? No real reason for there to be hundreds.
Same for word processors, spreadsheets, and other software. Just a couple of choices is JUST FINE!
Frankly, I think most of the time, there are just too many choices for most things in life. Think about the percentage of an average grocery store (and that's grocery store, not megamart that sells everything from car tires to lemons) shelf space that is dedicated to potato chips (and all their derivatives). My local crap grocery store probably has at least 50 different items from which to choose. Sure, choice is great, but I just want some damned potato chips! A few choices is fine!
I think the "regulators" need to get over (supposedly) trying to ensure that all the "small players" have a chance to compete. I say screw that. You're too late! You're too late to market, you missed your chance, and if you can't manage to get people to use your stupid phone operating system, web browser, chat program or whatever else, then too bad for you!
The very last thing in the world I want is for regulators to mess up what I consider to be a good thing, which is a WELL INTEGRATED STACK of hardware and software that I can depend on, and without having to make a bazillion decisions about this, that and the other, when whatever Apple includes is just fine with me.
