Whatever you think of the latest round of Chromebooks, school districts have clearly latched on to existing models. Over 500 school districts across Europe and the US are currently deploying the Google-powered laptops for learning the web way. Specialized web app packs and that rare leasing model are already keeping the material relevant and the hardware evergreen, but new certification for US ready-for-college criteria will go a long way towards making sure principals everywhere take a shine to Chrome OS in the future. That still leaves a lot of schools going the more traditional Mac or Windows PC route, with the occasional tablet strategy thrown in; regardless, we're sure Google doesn't mind taking any noticeable chunk of the market in a relatively brief period of time. We'll see if there's more reasons for Mountain View to get excited in a few days.
