Downloaded iOS 7 last night. I hate it.
iOS 7 is Apple's version of Windows Vista.
Gone are the bold type, and light blue backgrounds. Now you have fine type on a white background. I have 20/15 vision uncorrected. The washed out effect of the white background, and fine type gives me a headache after only a few minutes of use. Switching to larger type doesn't help either, you still get the finer print, only larger. I can only see that getting worse out in the sunlight. There needs to be an option for customizing the backgrounds.
Safari is another source of contention. Before you could select a full screen in landscape mode. Now you get the nav bars until you start to scroll down. Scrolling back up the page requires caution because if not done correctly the nav bars return until you scroll down the page again.
iOS 7, for all of its new features is not an improvement for the ease of use crowd.
For those of you whom haven't updated.......you may want to wait.....
