Why is it that my CPU goes 100% when syncing music/photos to iPad? I wipe my iPad quite often since I'm an iOS developer, but what I'm wondering is that why does my CPU goes 100%? Isn't it quite the same as copying music/photo to a USB drive (which doesn't make my CPU 100%?).

Granted I ticked the "convert to 128 kbps AAC" option, but for photos, I thought they'd only have to resize the photos when syncing?
Resizing the photo's is also CPU intensive operation.

Apple could potentially speed it up by using the GPU for resizing the images, but iTunes must be compatible with old Windows PC's. So I wouldn't hold my breath.
