I support a lot of iOS and Mac OS users. iOS 7 has been a disaster for some people. The overall engineering of the thin fonts and distracting motion and hip-hop colors has a lot of (particularly older) users up in arms. We've been able to overcome some of this with Accessibility settings, but it was still a poor job by Apple.
I hope Apple is much more careful with any final changes to Mavericks. We really can't take much more of this at the user end. For the first time in awhile, many of the clients are looking at alternatives to Apple again, because of iOS 7. Don't repeat the mistake with Mavericks, just when we're finally getting some Mac traction in the office community.
"We"? Don't include me in your nonsense pal...
"Many clients are looking for alternatives because iOS 7". You mean after the fastest sell of iPhones ever?
