for the same price, you get a larger screen, 25 MORE GBs of storage, video playback (unless they changed the specs of the Zen?)
Also I personally trust the name 'Apple' over 'Creative'. Creative may have a lot of experience in the audio world, I still just like Apple more.
unless... if the Zen supports more audio formats, then maybe it'll be more valuable... like possibly ogg. But I don't know what it supports.
