The SSD Review published a review on the Acer Chromebook C720 SSD Upgrade To MyDigitalSSD M.2 (NGFF) 128GB SSD A quote from the article:

If you are looking for a new computer and are a typical PC user, you need to take a look at the Google Chromebook. There are three brands of the Chromebook (Acer, HP and Samsung), it is SSD driven which means lightning fast startups and operation, they get anywhere from 8 to 10 hours battery life, and they are CHEAP! After spending a few days with this new Acer C720 Chromebook and getting to learn the ins and outs, I can honestly say that this is the simplest PC I have ever held. In fact, this will be going to my wonderful mother (72 yrs old) who has never had a PC before this. The person that will have the most difficulty ?refitting themselves? to the Chromebook, are us PC geeks that have gotten used to things just being a certain way.
