My chromebook replaced a netbook and an iPad. My husband has a desktop PC that I use occasionally and I use a desktop at school. Now that I've updated my iPhone 4 to iOS 5, I may not need to use my husbands desktop anymore , and I think chromebooks are a practical option for the classroom. I'll be testing my chromebook's 3G tomorrow. I'm taking my Samsung Series 5 on a trip to my in-laws' who live in an area with poor cell coverage.
