Not really iOS 7 comment, but I've used iTunes 11.1 several times in the past 24 hours and it seems a lot faster and reliable at finding and connecting to my WiFi connected iPad and iPhone. I had a lot of issues with 11.0 finding my iPhone 5. It usually took some effort to get it to find it. 11.0 NEVER found my iPad 3. Now every time I open 11.1 it immediately connects to both.
