Ok, here goes:
I tried torch as a main browser for a week now, and it's quite nice. =)
Basically, it's just like Chrome only with a couple useful features added to it - a Video button for quick download of online videos, and a built in torrent.
(There's also a Share button for quick sharing of the current page on facebook, but that's a pretty simple feature - so not that interesting...)
Video - catches videos from youtube and other services pretty good. I also managed to download videos from vimeo, dailymotion, etc. It downloads in the format used by the website, so you can't really choose which format you want. But - if you view the video in a higher resolution it will download in that higher resolution as well.
Torrent - the nice thing here is that you can download torrents just like any other file, and that you don't need an external torrent client. Even with magnet links - you click on them and that's it. The client is quite simple, so I don't think it's a perfect replacement for things like utorrent or vuse, but it should be perfect for users who don't want to complicate torrent handling...
Speed was ok...
All in all - it looks ok. A bit crashy, but my Chrome crashes too sometimes...
If anyone else cares to give it a try - I'll be glad to hear what you thought =)
