Unless there is some rule preventing it (ala Arcanum), magic and technology are going to be used together as often as possible. I don't think that you'd have mostly wizards and scientists ignoring each other. I think it's more likely that you'd have equipes composed of both, working on solving problems in ways that either approach by itself would find difficult or inefficient.
For example, making a self-guided car is very costly by magic (check the prices of any transportation items in the DMG - and they don't include heating, radio or airbags, and they don't go very fast) and very hard by technology (currently, we can't even get close to making a self-guided anything to which I'd trust my life). But you could make a normal car and enchant it so that it can drive itself, follow the driving code and avoid obstacles, and it would certainly be much cheaper. And let's not go into what any engineer could do if given the possibility of perpetual motion.
Obviously, this kind of applications are limited by the XP requirement of magic item creation. However, there are just as many ways in which a wizard could help the development and construction of technological items, without creating magical items. He would prepare his spells off a PDA, rather than a spellbook, though.
And what about the implications of widespread alphabetism and schooling? Cantrips could be taught in high school.
