Give us a break. You and others install Apps all the time to improve your phone. Anytime you install a camera app, music app, you jialbreak it or anything else you add to it from iTunes, you did it to improve your phone or customize it so please stop with that.Here's why Android users and iOS users are fundamentally different: I don't want to install a launcher or tamper with ROMs to like my phone, I want to like it and use it right out of the box. I've got better things to do than sit around trying to customize my phone all day.
And TouchWiz isn't just a skin, they themed the entire OS with their ugly cartoon icons and color palette.
You act like installing a Launcher is some big process. It takes no more time to do that than to install a game for which im sure you have many. I dont prefer to use Touchwiz myself so i have another launcher i use. People like you kill me. You damn well know if you could do things like use a different launcher or choose a different browser you sure as hec would and be estatic about it and claim Apple are innovators doing those things.
