I would also agree with trelson, we have been using it 2 years now and absolutely love it. Previously to that, we were looking at having to purchase 30-40 windows laptops as all of ours were old and dodgy, so we definitely saved a huge amount of money by just converting some chromebooks. We have had worries about it being cloud based, but it also seems to store it locally in the event of disconnecting from the WIFI. Only ever had one issue, but that was an issue on our end.
