I love the Remote App for iphone. I had too much fun this morning quizzing my wife with our music selection. I can do everything that is advertised on Apple's website.
I did have an issue with my network not recognizing it and communicating with my computers, but I figured them out and got it working. (AVG wasn't allowing the IP address and I had to restart iTunes after making the change.)
To me that is refreshing because lately many things are not want they appear to be. I could go on but won't.
If you have a sound system connected to your computer and love to play music loud and do housework get the Remote App.
You'll love it. I guarantee it.
