ok so i got my tax rebate check and i've been wanting to get an ipod with it. but i've been seeing rumors of an "update" coming this fall. should i go ahead and get one now or wait? i will be flying cross-country this summer and also a 5 hr drive later on in the summer. i teach/coach so the only other time i would use it is on bus rides to games or working out. right now i have a 1 gb creative and a psp w/ a 2 gb memory card. any advice? also should i get an classic or a touch? i really want a touch but is it worth the extra money/coolness?
