Never really filled up my 8GB iphone or my 16GB Ipad.
If you carefully chose your apps/music or video then 32GB is plenty. At the price of 64GB, practicallly a brand new notebook 750GB price, i wouldnt invest but its your money. However, u might want to wait a bit since Ipod touch naturally debut with Iphone and new Iphone is next week coming. There might be a price cut on Ipod or a 128GB.
really?? a new Iphone will be coming next week? Didnt heard that. hehe
thanks for the info! i think i'll wait a bit more just like you said
