Well, when your generation was born with many homes having computers like mine was, you really don't think twice about technology.
In answer to your specific question, iPods and MP3 players are basically like portable CD or tape players, except that they can contain lots of music, and they are very small and convenient. They're not a necessity by any means, but for music-lovers, they're a great way to keep the songs you like all in one place.
Blu-rays are basically high-definition DVD players. The DVDs for them are a little more expensive, and you really don't need one if you already have a DVD player.
People text instead of making a call because many people find it more convenient. Some problems you won't run into with texting is having the person already be on the phone with someone else, or not being able to hear them because of bad service.
Email is becoming obsolete because many people are now using instant messenger. Email is considered slow compared to instant messengers because it takes longer to send and be received. By the time an email has been sent and replied to, you could have sent and replied to dozens of instant messages.
I hope this explanation helped!
