Well, I just did a wireless sync to my ipod touch 4G and really love the convenience of it. At first I thought I was doing it wrong, since it took about 45 minutes for back up on itunes before I had to disconnect the ipod during the prep work to get it wifi sync ready. I worked great!! Had it going and also put a new album onto it without a problem!! Haven't tried it out on my ipad2 yet, will though when I have time. The cloud thing I am still questioning my need for that. I like to have things with me and not have to rely on constant connection to access data/music/photos etc.
