I used it once the day it came out and it seems like firefox with some built in bookmarks and a worse "new tab" page. I kind of like the video chat feature but I'm just like "why is this different than me bookmarking jitsi?" Similar with the other p2p features, it seems like there are already great websites for each p2p feature, and bundling them into the web browser seems to bloat it. I don't always want to video chat, so why load that code every time I run the browser? If I want to video chat I'll go to a site for that, etc. So it didn't draw me away from plain old firefox.
