why do you need iPod ?

I have an ipod touch, i have had one for the past (i think) 3 years. i'd say i really enjoy having one. first off, i feel good that I'm advancing with technology. With an ipod, mine is 8GB, i have 427 songs, 16 music videos/movies, 54 applications (mostly games) 200 photos and i can still add more. With an ipod touch you can view all the things i just mentioned, videos, music, pictures, games, you can also add your email. Yes if you have access to WiFi you have internet on there. Like i said at the beginning, you can put a lot of stuff in there which is why i enjoy using it. The only thing i don't like, is having to carry 2 devices with me all the time. I buy music because listening to the radio is good but if there is that one song you love, but they don't play it on the radio anymore or its a song from a movie that never was on the radio, i like to download music so i can have that song with me at all times. i like to buy CDs because the sound quality is better than downloaded music but thats another story! :P

-You can buy and iphone, where you can add music in your phone(just like your walkman phone), im not really sure how the iphones work, because i dont have one because they are expensive, i do want to get one.
