Re: paying for shiny...
You say "shiny", I say "better"

For instance, I'm trying an RSS reader, free & ad supported. I think I'm going to use it enough to pay the $1.99 for the full version. It's worth that for me to eliminate the ads.
But I haven't paid for any camera apps: they're cute for a day, but I don't use or value them to want to pay even a dollar for them.
It comes down to this: I want the best quality I can afford for things I care about. Incredibly, on iOS devices, you buy best-of-breed software for the devices for a couple of dollars.
I don't understand the false economy, though, of spending hundred of dollars on the best device for them and then hundreds more annually for the best data plan...and then skimp out on second-best apps (for things that the user cares about) to save a dollar? With a thousand dollars into the phone, why be bothered over a negligible $25 for a suite of top flight - yes, extra shiny may be part of that quality -apps?
This isn't an iOS vs android thing; I see iPhone users doing it.
