the one on the right is the new mac pro

similar approach in Czech Republic, and you can leave the tip separately.

sometimes during a call a music starts to play pretty loud from one side of the call, which renders the conference useless. I still wonder how that happens.

That's the old 'someone forgot to mute the call before accepting another call' trick. That's music on hold.

I was on a conference call once where that happened. It took over 20 minutes to figure out a) who the heck was doing that, and b) how to eject them from the call.

Oh dear. I've usually identified them in 5-20secs, but it takes another 60 - 90 seconds for the Host to block them :/

cheers, me too, except I am from Turkey.

I tried with Opera Next (12 alpha) but it was stuck in loading phase, and the lights were a bit slower than recent chrome beta on the loading screen.

Also using dot(.) to find in page and comma(,) to find in links are great shortcuts for browsing without mouse

Back around 2004 I was a heavy Opera user. One of the things I loved was the Z and A shortcuts to go to the Back and Forward.

I have tried to setup the same shortcuts in Firefox without success (actually, trying to personalize key bindings in Fx is a mess).

Have you seen KeySnail[0]? It's aimed at Emacs users, but you can use it as a general-purpose key binder.
