Also from my experience with Office 365 - it will be a pain to work on it. Outlook hangs up every now and there because it needs to update something from the cloud without any ability to open even emails that are stored locally. Imagine working on the system that is streamed from the cloud. And then they say that their employees became less productive for some reason..
Not sure what is the point of this thin client when nowadays you can buy a pretty decent full-fledged mini-PC for that price. You can also buy a less powerful mini-PC that could easily serve as a thin client for a third of the cost of this unit.
Microsoft has announced an interesting new mini PC for enterprise users. Unlike regular PCs, the Windows 365 Link does not boot Windows locally and relies exclusively on the cloud.
