I did a presentation on The Chromebook at The Connected Computer Meeting.
It is a different kind of computer, it uses chrome for it's browser (of course, it's Google) and is designed to work from the web. 99% of the time we are on our computers surfing the web, or doing our banking or on Facebook, Twitter, etc. We don't really need the power of a PC, with all it's requirements ( constant updates and virus protection etc.). With the Chromebook you never get a virus, malware, have to wait for updates or wait 2-5 minutes for it to come up.
I wrote my first computer program in 1969 and have worked on MANY different computers (including the IBM mainframe). I now use my Chromebook 99% of the time. I still have a laptop because some programs are not on the cloud yet, but foresee not needing to use it in the next year or two.
