I hope I am correct to put here!! Ipod touch or Microsoft's Zune is slimmer? Both have built in Wi Fi I suppose. Memory wise ipod Touch 16GB where as MS Zune 80GB. MS ZUNE is not available in Europe or atleast not talked about as yet. ipod touch is very much prettier and one can fit nicely in a pocket. Will it function as a PDA? I have not got either!! Not enough money yet but saving to buy one!!
