One of the biggest problems in life is having an idea but forgetting it soon after for lack of a pen and paper. Even if you do have a pen and paper, you have to remember to file it somewhere. Even if your phone has a voice recorder, it's still annoying to take it out and turn it on, then remember that you had saved a note on it.
Here's my solution:
You're sitting on the sofa reading a magazine when you get a brilliant idea.
"NOTE!" you yell. A voice-activated computer in the room turns on. You say your brilliant idea out loud. "END NOTE" you yell.
The computer transcribes what you said and emails it to you for future reference (along with an mp3 attachment). You can setup a folder in your email account designed to hold these.
Your idea has been saved forever with no fuss.
The only problem is it'll work only when you're at home, but I'll let someone else figure out the on the go solution.
The technology should all exist. Now who'll make it for me???????
