So it seems to be using llvmpipe eventhough better methods are available.

Judging based on appearance is not enough. One example: On a tablet computer you rely completely on the on screen keyboard. The on screen keyboard in GNOME 3 cannot be relied upon. A really reliable on screen keyboard would be great for accessibility reasons... Now if you really use a touch interface, you'll indeed have the same thing with GNOME 3 as with e.g. Android. But with either a mouse of a keyboard I don't see any difficulties. Obviously it works differently, but I have an Android phone and use GNOME 3 and the experience is not the same.

I tried it under Fedora and it was not slow. Currently we're long away from a stable release so IMO it is the right time for some testing, but it should at least not use llvmpipe when something better is available. -- Regards, Olav
