If you plan to use this computer longer that a year or need to store a lot of information, PLEASE DO NOT BUY.  I have had my Acer Chromebook 15 for a little over 2 years and have been fairly satisfied, despite the many limitations of Chromebooks, until I learned that this device will do you the favor of deleting ALL downloaded files when it begins to run low on space.  I realize that a device can only hold so much information before you have to move it elsewhere (The Cloud, external hard drive, literally anywhere but this computer), but a little warning that all of my files that I use for work, proof of CEUs, and other documents that I no longer had access to, besides in my personal files, were going to be deleted would have been very much appreciated.  The computer still works great, but what a terrible design!  If you want to keep the files that you have then do not buy this.  Its cost efficiency does not make up for its limitations or its "self-cleaning" mechanism.
