Hi, I am looking into purchasing a 2g Ipod Touch, mainly for PDA purposes. The various apps available now have swayed me toward buying. I would appreciate any comments on this subject. I am also forked over which model to purchase. I don't see myself listening to much music or watching too many videos on the device. Should I still play it safe and buy a 16gb model anyways? Apps don't eat away memory too much, do they? I appreciate any replies.
