I have been using Apple products for the last 15 years, and I personally have a preference in how well the operating system of Apple products stands out against all of it's competitors. When I first started using the Mac it was running the classic mac operating system, or Platinum rather. When I got my hands on a copy of the first version of OS X I was informed that I shouldn't install it on my main machine because it is a little buggy, but I went ahead and did it anyhow even though I had one computer; that being my main machine.
Ever since laying my eyes on the Aqua interface I haven't seen a better looking user interface come along. Granted Apple has changed the look of it through the years, certainly for the better, but it always gives me a feeling that I am using a superior interface. One look at any version of iOS and you can quickly associate it's features with Aqua.
There have been a lot of rumors since the departure of Scott Forstall, and the control of software design being handed over to Jony Ive that iOS is going to see a radical overhaul. I would assume that OS X would follow suit, if not in 10.9 but in version 11. I for one do not like what I am hearing about the design direction, and I have seen mockups, and supposed leaks of the actual icons. These "leaks" look as if Apple is stealing their designs from Microsoft Windows 8. Personally I hated the look of Windows 8 when I first saw the screens of the OS. Everything in these flat designs seem so uninspired and generic.
WWDC is less than 12 hours away so we all will know soon enough the direction that Ive has decided to take iOS. I can only hope that he has not tried to do so much of a dramatic change in the little time he has had being in charge of the interface design. I would rather that iOS 7 and iOS 6 look exactly the same if I can have an iCloud that works better than what we currently have.
