I can think of some. A lot of people use browser almost exclusively at work. Salespeople, customer service people, etc. If the business software they use is web based, they use a browser.

I don't know, what if they need to edit a report with a company template someone made in Word? There are full fledged PC for sale at less than that price. Salespeople are often on the move and would probably use a netbook I think.

How do businesses currently share Word docs? They either email them around or put them in a shared folder. And when that happens, and the ChromeBox user clicks it, GMail or Google Drive will happily open that Word doc in Google Apps.

I may be mistaken but I don't remember being able to keep the template of a word document while editing it in google docs, changing examples anyway, slightly more complex excel files could also not be supported I think.
