under the view more specs it gives the model number CB315-4H-C7A1 and this is what google has about that model-

The Acer Chromebook CB315-4H-C7A1 has an Auto Update Expiration (AUE) date of June 2031

It's a good price for a 64GB hard drive with 4GB of ram, if it wasn't for the fact that I pretty much decided that I love the having an actual pc, dislike the small size of a laptop and the tinny sound on them, I'ld buy this one.
