Liking the aesthetic changes does not make one love iOS7. Live wallpapers, quick toggles, these are only parts of the Android OS. 3rd party apps as default, widgets, customized interfaces (i.e., keyboards) are just a few of the system level differences that aren't apart of iOS. These changes are largely superficial.
Hmm, this is only the first developer preview and you are already judging it.
And home screen widgets is a bad idea IMO. It just creates unnecessary clutter, and you'll need to exit the apps to see them. Thee are better ways, and iOS 7 seems to do it.
As for the customised interfaces, that's something for android users. If you want it, get an android phone. iOS is for people like me who couldn't care less about customising their interface. It's better to have choice than to have them both doing the exact same thing.
The main thing is that they liked it: the looks, the apps, the functionality, and the implementation.
