Downloading and installing now. Going very quickly, actually.
I have one gripe. Wifi syncing is great and all, but really, since the computer it syncs to has to be on AND the device must be plugged in to a power source, what do I have to gain?
I still have to turn my computer on either way, I still have to plug in my iPhone either way, and so I might as well just sync it via cable and save myself some time.
Same for my iPad that's synced to my MacBook. If both are portable, and both have to be on the same Wifi network, and my iPad needs to be plugged in, I might as well sync it via cable.
Even if I plug my iPhone into the dock that's connected to my TV downstairs, I still have to go upstairs to turn my iMac on. This will be an unused feature for me, I think.
