Google - I know Ive gone on about this in the past but get a gmail account. Some of the other cool things you will get include:
- A blogger account :)
- Personalised Google.
- Google Co-op. - This allows you to make your own search engines. You select what sites you want to search and it does it.
- Google Pages - Free website hosting with a dead easy website creating tool
This will make you think. Once it gets onto the computer stuff you can more or less tune out though, its all just guesses.
