Chromebooks are great for kids and anyone who is on the internet more than anything else. It will also play movies and there are some apps that replicate common programs. Like you can write a report and do a spreadsheet. It just needs an internet connection all the time.
Honestly I really liked Netbooks, and do not get why they didn't take off.
I broke my three year old Toshiba Net book only to find out Netbooks are a thing of the past.
