Yep, Ubuntu is mainly targeted at new users and switching Windows users but yes of course experienced users can use it.
There is a third party openSUSE 11.3 NVIDIA driver repo but I'd wait for the official one. Fedora's rpmfusion package the NVIDIA driver quicker then this!
BTW, Boot and login is a lot faster now as well I've noticed. I see they're still reliant on HAL. I installed the DVD version.
My desktop is set-up how I want it.
