Exactly!
The difference is the same information readily available when I want it versus having to go seek out that information (in an app) and then wait for everything to download. Like I said, everything is readily available already there on my device as soon as I turn it on. No need to open different apps for different things, no need to download anything, it's all already there. The solution you just named is clumsy and cumbersome. For what you just stated, I'd be going to different places throughout the phone to get the same information that I get a at a glance on one screen. Bear in mind, if I'd like to I can add other things also. So I can have whatever information or controls are important to me right there readily available versus having to go into different apps and menus just to achieve the same thing I can at a quick glance. So no that isn't the same. Bear in mind I didn't even mention my other pages that have things like power controls to toggle different features, control pandora, control my music that streams from the cloud, emails, and google voice controls. All this information and controls are all conveniently placed in quickly accessible places on my home screens. In the time it takes you to open an app and do just one of those things, I'm done addressing everything that I want to. That's the difference that customization makes.
The temperature as an icon is nowhere near the same thing.... Also why does a person have to be a "fanboy" because they do see things the same way you do? The topic of customization was brought up, some people tried to minimalize it, and I'm simply making the point that it is indeed useful and adds to the user experience. If you can't seem to understand that I can make a point without being a fanboy then I don't know what to tell you. I've owned lots of high end gsm phones INCLUDING the iPhone, and the bottom line is I find the iPhone to be an inferior device TO ME due to it's shortcomings. I buy and sell iphones all the time on the side but I don't find it to be adequate enough to be my daily driver (for a number of reasons). Everyone that doesn't agree with you isn't a fanboy. Don't like that my perspective isn't the same as yours? Get over it. We still have iPhones in the family so I will continue to use this site and I will continue to offer my perspective where appropriate.
