Some things I noted about it:
- It took a long time to connect to many web sites.
- It crashed a lot
- There was no tab interface... opening a new tab worked, but you couldn't close it or get back to any old tabs.
- It caused google to block me
- No dialog boxes worked... couldn't open the options pane, no about pane, etc...
In short, the browser is not usable yet.
P.S. As you can see in my screenshot, there is a big disclaimer that this browser is NOT READY YET, so DON'T judge the quality of the linux port of chromium using any information you can get about it today!
