I love how all the android fanboys come in here to beat their drum...its just like the iPhone forum...
But really though, who cares? Buy what works for you. If android works for you, cool. I don't care what android has or doesn't have, nor what you think about it, so keep preaching your fanboy drivel somewhere else, or its just another hidden poster. If you want to talk about the actual issue at hand here, and how it relates to the iphone without spewing all your fanboy bs, then awesome, that's what this is meant for.
Both OS have their merits, and faults. Anyone who denies this is clearly of a less capable mental state. It's different strokes for different folks; whatever works for you. As for the "freedom" fighters, well, you're a bit out of touch. Keep pounding that freedom drum there, in your own little world, nobody's listening.
As for the actual security aspect; it is a legitimate issue. While yes, you do have to confirm access to data, you have to consider that the public at large isn't very bright, and will probably just download anything anyways because it looks cool or what not. This means only the intelligent and reasonable are protected, which sadly is a minority. We see this time and time again on the windows platform; people download trojans and what not, then execute them to boot, because they're not the brightest crayons in the box. Windows can be a perfectly secure and stable system (especially win 7), yet users still have issues with viruses and spyware from user error. Hence the main issue with android; while some people won't bite, many will, creating the potential for a large security issue.
