Let me back up. The majority of educational software is now web-based. 90% of middle and high school computer usage is either web based or using a dedicated word processor. It's not the Asus specifically that has us interested, but the concept. If you've seen the Asus, it's really more like a web appliance. The average person would look at it the same way they look at the iPhone or an ATM machine... they don't know or care what the OS is underneath.
So for education, this could be huge. As competition increases and these devices get down to $199, the previously expensive idea of "one laptop per child" does not seem so expensive any more. There are three groups of people who need to be paying close attention to this: Microsoft, Apple, and Textbook makers.
Put this together with education's interest in "Web 2.0," aka "The Read/Write Web" where all your school books and files are available to you online anywhere, and you're brewing up the perfect storm. Apple should be working on a device of their own right now, if they're smart, and Microsoft.... Microsoft should be praying.
