Here is a computer from BellSouth Wireless with full keyboard (that your thumbs take to with no training) that is smaller than a garage opener and fits easily in your pocket. From it you can send instant email, faxes, and even voice messages to a phone number via PacBell's text to voice system. It's truly interactive with a response time for messaging of around 10 seconds. About $50+ per month.
