I have had a samsung chromebook for about 6 months. I bought this as an internet surfer, and have really liked it. If that is what you are looking for, then I think the convenience and cost of the chromebook are tough to beat.
The biggest thing to keep in mind is that only software you can install are apps from the google webstore. You cannot install any independent 3rd party software such as itunes. Its essentially and android smartphone in laptop form. The upside of this limitation is that the computer if very secure, and less susceptible to virus, malware or other threats while surfer the web. Downside is that if its your only laptop you may not be able to use some needed software.
