I got homesick a lot. Can't do without this memento from home. Every trip I go to starts with me landing at the airport and thinking - fuck this, let's go back. Regardless of whether its Yosemite, Vancouver, NYC, Singapore, New Delhi, Costa Rica.
I'm not an Apple fanboy but I've had that iPod for years and it works awesomely. Battery life is down to about 8 hours but I hear replacement batteries are on the order of $15.
