It's Beta but what you see is basically what you are going to get this Fall.
Apple is not going to re-change it all over again in the Fall. lol
What I like:
Control Center-quick toggle of bluetooth/wifi
new tabs
swiping
What I don't like
Color Palete
Flat has turned too basic, too childlike
Too much white background in almost everything, safari, keyboard, causes some of the buttons to become faint, safari only offers a darker scheme by using "private"
To be honest, the new color palate with pale pinks, baby blues and neon greens is just too much, ok for a girl though but it's too basic. The color scheme alone may be a deal breaker and keep ios 6 instead of upgrading. Where are the rich reds, dark black, grays and vibrant colors we love about ios 6, there gone in ios 7.
Apple was innovative with ios when iphone was released 6 yrs ago and they could have been innovative if ios 7 had been released 3 or 4 yrs ago but so many of the new features in ios 7 are not innovative or exclusive.
However with Apple when they release something new it does work and work well everytime you use it, dependable and reliable. So ios 7 will be a success just doesn't seem groundbreaking to me.
