Okay bit of self site promotion , we reported on the Flock browser earlier this week, I've not had a chance to play with it personally yet but it sounds interesting.
it looks like firefox with a good skin the only glaring problem that i have is that it can import only IE bookmarks as default. it does not import FF or opera bookmarks. thats just silly, especially it being a FF clone. also if u have a deli.cio.us account then it adds ur links to deli.cio.us and u can have the same links on differrent computers provided that u use something to retrieve the links. i think its targetted mostly for bloggers and such people. you can integrate a flickr account and also u get a wordpress blog free with it not much use for me, but its a nice util for bloggers.
