Re: "reliant solely on Apple"
Right, and not just for "a decent replacement" either, but for OS updates too, which Apple has a habit of arbitrarily cutting off when it wants you to give it more money (planned obsolescence).
Meanwhile, my two year-old SGS v1 is running ICS, regardless of what Samsung wants. You can only do that with Free Software like Android. That's the whole point of it.
Another thing to bear in mind is you can switch Android handsets as often as you want, between many different makes and models, and you get to keep your apps, just as you would with Windows or Linux if you switched PCs from one make and model to another. Whereas if you switch from Apple's closed ecosystem to anything else, you end up having to replace everything.
Between those crucial points, and the seemingly permanently dysfunctional state of Apple's "high quality" hardware, I find it astounding that anyone buys their products at all. There must be an awful lot of sheeple easily swayed by marketing propaganda out there.
