Hustle Is right one the money! if you wait for technology to get better it will but you will NEVER be satisfied because as soon as they come out with the NEW one then another NEW one comes out, just pick one your comfortable with and be happy I've been waiting til the iPod touch 32gb comes down in price cuz thats all the storage i need so I'm getting one for Christmas but waited a year to get the one I want and am comfortable with.
32Gb will be good enough for me for the next year or two given the way i only add the occasional track every week or so.. My music collection is definable and doesnt change that much, only increases a little.. 32gb would be perfect for me.. absolutely brilliant.
