Ingenious speech to text tool or cyborg nation?

The web has and continues to transform the way we interact with the world. One area that is of increasing interest to me is how digital media is augmenting and some cases replacing biological media. For example, you may have no clue what computer vision is but you can quickly find out by visiting wikipedia or a local library. Is your memory of the topic computer vision stored in your brain or the web? This example is clearly at one end of the spectrum. At the other end you can find brain-computer interfaces which allow some blind people to regain vision through direct links between computers and the brain. In any case this area of inquiry is fascinating to say the least, but I digress.

Reqall

Reqall is a service that allows you to record a voicemail which is then transcribed to text and emailed directly to you. It is totally free. The messages are stored on Reqall's server if you would rather retreive it there. Additionally, you can have a group receive your messages, which is handy for shopping lists etc. It is a simple tool that works wonders.

Reqall is especially good if you are driving. Normally, you would have to write down a note on your PDA or piece of paper, which is sketchy the way I drive. With Reqall on speed dial you can quickly call in a message to be emailed to you.

Reqall is also great if you have memory problems. I seem to always forget little things because they pop in and out of your mind at random times like when I am driving or right before I go to sleep at night.

There are several other services that do the same thing. Jott, dial2do, Spinvox, PhoneTag and more. I haven't evaluated these although I know most of them are paid services.

What if everytime you think of a task you use Reqall instead of your brain? Over time I think it is bad for your memory. How many of you can actually tell me the phone numbers behind your cell phone contacts? Does it matter? How long until we have a little hard drive implanted. You could argue that laptops are the begining of this anyway.
