I think this was well answered in a post in the previous link's comments:
"Allowing things to run in the background on a cellphone (a device so private) is worrysome.. sniffing data (if technically feasible).. eavesdropping calls.. (if technically feasible).. routing to different nets (if technically feasible)
.."
And
"
Reliability is king for mobile apps"
Just for the record, I am not saying that I know so much about mobile apps (definitely interested for sure, as of yesterday evening), but I just believe it might be a welcome change to the smart phone business if there is some control and stricter guidelines for a few things.
I've had a crappy Nokia E61 in the past and if you had as much as installed
Tetris on it, Nokia was fast to point out that they would take not a single look at the crappy device as to why it kept jumping off WiFi networks and what have you. I've had dozens of Nokia horror stories. Not one glitch on my iPhone. That doesn't make me a fanboy more than the fact that I prefer things that work reliably. And it happens to be that my experience with Apple products far surpasses anything else tech-wise on the grand scale. Nothing is perfect, but show me a manufacturer that's closer.
I'll take a slightly slower adaption to new and "what's technically possible" anyday if it comes with reliability.
And for those mega-tweakers, I'm sure Microsoft and Yahoo will come up with something that makes you all happy dancers. Think - what's the name again... Zune-Phone or whatever...
