Yep, this has been a huge disappointment for me.
Wi-Fi Sync requires you to be on the same network as the host computer and be plugged into a power source. You're as well just plugging it in to your computer using the USB cable... which is what we have always done!
Let's be honest, if you have your computer on, are needing to plug in your device and want to sync stuff, there's no real scenario where you would have the device plugged in to the wall socket while syncing with computer in the other room. I'm sure there will be some people who will do this but it's hardly going to satisfy the masses - most will just plug it into a computer.
In my opinion, Apple know this is a battery drainer and are scared to introduce true wireless syncing as they know it will mean they have to advertise decreased battery life times.
