In Oblivion my character had shield and sword AND he also had a destruction spell equipped. I liked fighting with my sword+shield and occasionally, when I pushed enemy back or I backed off I would threw a flare at him. That was my main way of fighting. I regret not being able to do that in Skyrim.
EDIT:
also does anyone else think this is going to feel kind of weird with a mouse? like on a gamepad RT is pretty much the default attack button in every game but on a mouse it's left-click, which in Skyrim's case will likely be controlling the left hand.
I think it'll be something like LMB for a weapon in your left hand and RMB for a weapon in your right hand.
