When I was a kid,
Then:
*You need to have a film camera to take pictures and an expensive video camera for video.
*You need to go to the movie theater to watch the current movies and to a video store if you want to watch movies at home. You need a portable DVD player if you want to watch it anywhere else.
*You need to go somewhere? You need to visit that place.
*You need to call someone? Call them at home with the landline, and if they are not there, you need to write a message for the one who answered (no voice mails then). If you are outside, you need to call them with a payphone, but you need a card or coins.
*Unless you have Caller ID, you will never know who is the person who is trying (or tried) to reach you. You will never know how many missed calls you got.
*You need to play music for your school dance? You need to bring your big-ass radio with CD player + all the CDs you need.
*If you want to bring your books to read outside, you need a bookbag.
*You need to bring your Gameboy, if you want to play games outside.
*If you want to use the net, you have to find an internet cafe outside, or use your bulky desktop computer with dial up at home.
Now:
*Your phone has a camera and video recorder that is better than most digicams, some even in HD.
*You can download movies into your phone and watch it anywhere.
*Everything is online.
*You just need to call them on your mobile. If they don't answer leave a voice mail of text.
*Every info about the caller and missed calls is available.
*You just need to bring your phone and a stereo dock.
*All the ebooks you need are stored into your phone.
*You can play games on your phone, even nintendo ones.
*Your phone is better, faster, and have more memory than your desktop computer, which you can bring anywhere.
The biggest change is how you communicate with others.
When I was a kid, unless you have them as your neighbor, you only get to see your friends in school. You need to call them at their landline to plan any activities. You need to be at that place at the exact same time because you cannot change plans at the last minute.
You need to write letters or expensive out of country calls to keep in contact with your family abroad.
Now everyone is one text and call away.
