I was finally able to upgrade last night after first trying at 2pm and getting an error message, I kept trying like 20x every hour, finally getting it to install around 8pm or so.
I like pretty much all the new features, its the funky colors that are bugging me.
Previously, the colors used to look sophisticated and "adult" looking, if you will. Now they look like a 14 year old girl designed it from a box of crayons, as the color options and the phone and messages icon colors was the best GREEN she could find...
Even something as simple as the settings menu, which used to look nice with different layers and colors, now looks plain as can be, without any graphics.
I guess it will take some getting used too, as with everything NEW. It will have to grow on me...
I still can't help but think that iOS 7 was designed more for the iphone 5S, with the faster processor. Some of the new features just seem to lag and take 0.001 of a second too long to load / respond. Seems like the old iOS worked faster. Maybe it's just me though.
I hope Apple changes the colors a bit in the upcoming updates as the current setup is too fruity looking for my taste, as a MAN!
