So if it requires a browser and an OS to run it on, what exactly does it provide that I don't already have?
It's an unusual concept. I usually avoid cloud-based BS like the plague, but this seems... I don't know, different.
I signed up and logged in to try it out for a few minutes, seems it's basically a modern Amiga-like OS in a web browser. But they're also doing some rdp black magic to allow you to run applications from multiple OS's (including windows) in it.
You can mount web-based storage (sftp or google drive are a couple) inside the OS as well, I couldn't make it work, but admittedly I didn't try too hard. I guess the selling point is you can log in from any device with a browser and access the same desktop session on all devices without actually having a PC. Like a weird hybrid of a remote desktop session and a thin client.
Unsure what the fuss is about tbh, but I'm intrigued enough to try it again in a few weeks
