I was wondering about this, myself. What is your opinion/preference?
Well, my main concern is that if he's running around making TVs and AK-47s, the world would know about them and wouldn't still be stuck in pre-industrial stasis. Plus, you need an entire industrial base to make tech stuff; you can't make a computer without a technologically advanced civilization to mine the ore and put it together.
But... If we can morph mortals into freaking dragons, we should also be able to morph them into, say, a cyborg with a gattling gun for an arm and an advanced AI advisor on board. So all the character's tech would have to be physically part of him. He would also have to go full Brotherhood of Steel, hoarding all technology and killing anyone who tries to copy his stuff, to explain why we don't have spaceships and computers by now.
