I use Callwave Text Messaging. I found it in the "Add Stuff" section of my google home page.
- You can use MSN Messenger and add someone's mobile as a contact. When you IM the person, they receive the message as a text messages, not as an MSN instant message.
- As of right now there is no way to actually read your text messages from a computer.
- you can also e-mail them to yourself
some people can and some people can't and some people text them by email
