hello all, i plan to buy several iPod's (shuffle) as gifts for friends. while the current 4th generation shuffle seems quite nice, a friend pointed out that its been around for a while now and apple should be releasing a new version soon. does anyone have more info about this? if not where can i get more info on the same? i called apple but the agents said they have no idea. on the other hand, i am wondering as to the changes apple will make with a new shuffle. the present model seems to be quite nice and it looks to me that a new model might simply have cosmetic changes. so, any ideas when the new shuffle will be launched? and the new features/big changes it will have. thanks!
