We are still in the midst of a computer revolution. But I sense a curious inertia among the computer-using public, unwilling to keep learning. One hopes we are not weary of progress. Here are a few things I do which improve my life or finances or convenience which others seem unwilling to do, and I'm unsure why.
Skype. Free telephoning on the internet. It requires a trip to a consumer electronics store, a computer with little input-output jacks, the internet, and the microphone and or speakers you buy at the store, which you likely will be surprised to find very inexpensive. Like under $16 for both if you are lucky. Peanuts in most cases. You find Skype, log in, they test your little rig, and you are on. It's free. You talk to other people like you are on the phone. They are on Skype. For free.
Besides Skype, there is something completely different: emailing to your friends' text messaging phone. That's right, if you are at your computer, there is an email address you can use and send them a text message on their phone. It's usually something like 9082345678@Sproink.com. If you are determined to find it you can. Obviously you explain to your friend when you do this. They might be interested in this ability. You can check the Google on "how to email text to Sproink customers" or "Dingdong customers," or "Mojorizen customers." You'll find it. That way you can text them without using your minutes.
By the way, those texting maniacs can also send texts to your email inbox from their phones. Instead of a phone number, usually they can send it directly to your email address. And note that's true even if they don't pay for internet access on their phone plans. If they pay for texting, they have this option. Hey, it might cost them a dime but it's better than both of you paying it. I think text maniacs have a certain number of texts they can use anyway.
Of course you can also send free homemade audio files via email just like leaving a voice mail message if you prefer to talk. You have to download a free audio file program and use your microphone to speak a message. Attach it to the email. I've done it, and it's been appreciated, but I have other options such as Skype. My minutes are so over the limit now, I might do that with a friend who prefers voice contact.
