There are several built in features on the iTouch that I find very useful for practical purposes and I’ll discuss them here:
ALARM CLOCK (AND WORLD CLOCK)
Alarm: I used to travel with a travel alarm clock but since the iTouch has an Alarm Clock feature, I no longer have to bring one along.
The contacts feature is good for keeping all of your contacts in for easy access. I usually do a specific document containing all of my itinerary contacts and load them onto Airsharing. But this feature is great for bringing along your contact information for family and friends.
IPOD (MUSIC & MOVIES/VIDEOS)
The IPod feature on my i-Touch is a great source for entertainment. I have my library of favorite songs and playlists to while away those pockets of empty time spent waiting for flights and on train rides. I have also been able to learn to convert my favorite DVDs and movies to be able to play on my i-touch and ipod.
Sometimes taking a little bit of “home” with me on my trips keeps me from being homesick. So bring along your favorite music, your favorite artists and your favorite videos and stay connected and entertained.
Note: This feature allows me to type out short notes when needed while traveling on the fly.
While in the Prado Museum in Spain, I used to it to type certain notes about the art that I was seeing to remember my thoughts and experiences.
