They reinvented thin clients. Expensive ones, with an extra Windows license needed I suppose. How revolutionary...
These over a (possibly flaky) internet connection is another.
Maybe in some countries/cities/locations where there is a "perfect" conection they may work, otherwise the 365 part of the name will need to be changed to the low 300's.
The latency can sometimes cause issues, but for the most part it works and people are able to get things done.
If Microsoft can get the latency down to what I get using Game Pass, I won't even notice that I'm using a remote machine as long as I have a working internet connection.
I'll see myself out!
