There will be a $150 laptop on the market by 2007 but it will have limited capablities. It will not have a Microsoft operating system or a name-brand processing chip but it can be used to surf the net and send and receive photos:

An Atlanta company is cobbling together diverse software and hardware building blocks to create a $150 laptop computer that promises its users a common computing experience and avoids Microsoft software and name-brand PC processors like Intel and AMD.
Called the “LiteComputer” by Lite Appliances, most of the pieces of the laptop have been developed and the firm hopes user models can be ready by mid-2007.
“We are developing a device with a complete computing experience without all the overhead,” said Jack Knocke, senior VP of business development, in an interview Tuesday. “It comes with all the hardware and software that you need. You can surf the Web, send and receive photos. Also, there’s word processing and spreadsheet capability.”

I could see getting one for Samantha (of course Sarah would freak out if Samantha got a laptop four years earlier than she did).
