well, after years of admiring the iPod but then going all sensible and saying to myself "well, you wont actually use it will you" i've finally decided to get one once i found out i can connect it seemlesly with my car stereo so, this 30GB iPod Photo... is this the one to get? i certainly dont need 60 so the size is right, and its nice and slim... i read in the write up tho that it has a click-wheel, isn't that the kinda wheel thats on smaller/cheeper iPods? i thought the proper ones had touch ones where you just rotated your finger round? the only reason i'm posting this is so i dont buy it then for someone to go "oh you didn't buy the iPod Video did you??? you shouldn't have for x y or z reason..." not gonna be superseeded soon or anything is it?
