I'll stick with my original expectation, that moderately crummy Google branded Chrome OS machines will sell for under $180 with battery.
If that happens then Chrome OS laptops will be huge in K-12 education, 23 years after I mercifully failed to sell a rural school district on a student Newton OS mini-laptop education model.
Huge, that is, if Google gets Parental Controls right. I ain't giving my kids Chromebooks unless I get full control over what they get to and what they do.
If we don't see Parental Controls emerging in Google App domains within the next six months, the Chrome OS may be missing an essential function.
